Maybe buy him a baseball glove or a frisbee- something to spur activity and interaction with others. If he's a tech genius, the last thing he needs is a computer- he's already mastered that.
Call your local homeless shelter or charity. Maybe they could use your netbook to get someone on their feet again.
Lighten up, Francis....
I wasn't challenging the laws of thermodynamics, I was challenging the parent comment "It is currently illegal to resell electricity that you generate using waste".
As for my resume', I'll spare you the details, but my background is in energy and energy transmission contracts- more specifically, natural gas sourced co-generation.
Besides the "illegal" comment from the parent post, the statement "You don't have much incentive to install a way to reprocess that heat", is BS. There are thousands of facilities here in California selling electricity produced from 'waste' heat as a bi-product of their primary business. There are incentives for doing this- specifically, decreased natural gas transmission costs for BTUs put back on to the grid in the form of electricity (electricity that they market themselves or sell through marketers). Check out http://www.cpuc.ca.gov/ and search 'cogeneration'. It's a huge industry here in CA and is heavily 'incentive-ised' and subsidized as an alternative to building power plants.
What? You better tell that to the thousands of dumps across the country burning 'waste' methane to produce electricity to sell.
Many industrial facilities also produce energy from waste heat and manufacturing bi-products. It's called co-generation. For example, many cement manufacturers burn natural gas (among other things) to produce lime-ash. They take the waste heat and produce steam to turn generating turbines, often producing more electricity than they use.
HP ProCurve has dual radio products from their buyout of Colubris... check out the MSM422. You can run 2-3 of these @ low to mid power with one radio on N (@ 5ghz) and one on b/g (channelized). That should split the traffic up a bit (most newer laptops have 802.11n cards) You should be able to get 200+ users per AP as long as no one tries to connect from the parking lot (hence the low power).
You can also use some narrow-field sector antennas and "columnize" your signals across a room.
If it is a more permanent installation, consider a distributed/engineered antenna solution (DAS) that will limit the signal bleed outside the intended area (and in turn, increase the connected capacity of the AP. DAS solutions get expensive though. So unless you have other signals you want to inject (cell, licensed radio, etc...), this may be out of the cost range you are looking at.
And for the record, I work for an HP reseller (we sell/support other vendors as well).
A written summary greater than a paragraph or two (or 2 minutes in front of the board) just won't be read.
Metrics. Give them big numbers (like database queries per hour, or something like that) and small numbers (latency, downtime, whatever).
More importantly, give them something that they can take to the golf course and brag to their buddies about. Anything that can make their dicks longer or boobs bigger than their peers will win you much praise.
Finally, many execs I have worked with over the years just don't care about I.T. until something breaks or money is about to be spent on it. For these folks, I keep metrics that can be graphed or otherwise presented to show trends, stability, uptime etc.

- Unlicensed spectrum is prone to interference and incredibly easy to DOS by simply firing up another AP.
- Your connection on any given AP is only as fast as the weakest, slowest connection on the same AP.
- limited frequency range limits AP density
- supporting wireless in the enterprise is about the biggest headache one can give themselves.
- iphones.
that is unless your residential ISP blocks port 25 outbound at their gateways (and it seems most do nowadays), then you are somewhat bound to at least relay your outbound messages off their servers... TLS doesn't protect much at that point.
No, 5000+ hosts do not need to be *directly* accessible from the internet, but there are an exponentially growing number of devices and information stores that need to be accessed by vendors and business partners (a good example is the change to digital diagnostic imaging by many hospitals over the last few years- those images have to move from hospital to hospital and hospital to clinic somehow). While solutions like Citrix or SSL VPNs are solving many of these issues, often direct VPN access is the only solution. With the VPNs, classic LAN-to-LAN tunnels within NAT space (RFC 1918) are not only prone to conflicts, but are complex to secure. Landing VPNs on routeable addresses outside the firewall (then pin-holing) is most often the only logical choice.
In the specific hospital case above (and this problem exists in many more industries besides healthcare, I'm sure, but healthcare technology is my area of experience)- based on the growth of connected devices, I will be out of IPv4 addresses in about 2 years. Maybe I was a bit loose with my 'wasteful' comment above- but in hindsight I am glad I hoarded when I did. Those remaining 300 routeable addresses are becoming precious. The days of handing out large IPv4 blocks are over as far as ISP's see it, so do I start hoarding more IPv4 addresses now? Sadly, I will probably have to, even if I am charged a nominal fee; it will most likely be cheaper than implementing IPv6, at least in today's skill-set market.
I don't know which ISP's or upstream providers you are dealing with, but in the last 2 years, every DS1/3 circuit I have ordered required quite a bit of justification for anything more than 5 IPv4 addresses. No, I have not had to pay extra for addresses yet, but I have been told by AT&T and others that
