It might take a while to get 1Gbs+ Internet to most homes, but for LAN i feel GbE as a bottleneck today.
When I use DLNA to stream HD content to 3 TV's (one in kitchen, one in living room and 1 or 2 in kids rooms) and use N spec wifi at the same time, the DLNA lags sometimes. By calculations there should be some bandwith left over but not much. The lagging is probably caused by unexpected overheads and GbE switches preforming at "GbE in theory" speeds, but with the world moving towards a phase where every single gadget/device is connected to LAN/Internet this will become a large problem shortly.

The project will likely take 5 or more years to complete.
I remember having 4mbps/512kbps ADSL line 5 years ago and there is no way i would call that "usable" today.

I've had 150mbps/100mbps cable for a year now, this seems fine at the moment but in 5 years? considering how technology keeps on advancing and using up more-and-more bandwidth i really doubt there will be that many users for 100mbps net in 5 years.

In my opinion they should take the money, invest it in backbone networks and let local telco's compete on rented cables (take Stockholm for example, similar scenario resulted in 4$/mo 100mbps net for the whole city 2 years ago)

There are two huge problems with this kind of subscription system:
1. How do would they charge you?
- They could book the maximum possible amount ($15.95) up-front but that would result in constant booking on your CC
- They could charge you every time you enter the next level in payment structure, but this would increase the payment overhead fivefold
- They could charge after a period of playing but that would result in massive number of botters/farmers using fake CC details

2. This is exactly the kind of subscription model that APB had and was one of the main reasons for their failure.
People don't like to be presented with options like: "will you be playing 1-10, 10-20 or 20+ hours this month?". MMO's are supposed to be entertainment for free time. Planning ahead "10-20" hours of entertainment will make it feel like work.
It is much more fun to pay $15 and play as much as you like than to constantly worry if I'm going to loose money by playing too little or too much.

But this is already happening isn't it?
Unless you took the blue pill...

Consider opening a media file, with your trusted program from SMB. If the attacker has planted a malicious .dll file in the same SMB share and your "trusted" media playing application is vulnerable then you have just compromised yourself.

There won't be any functioning games left for 360 in 5 years, so you don't have to worry about that.

I was part of a team that created similar (but a lot simpler) algorithms over 5 years ago.
15 years ago you could create a algorithm and let it run for years and it still would be profitable.
5 years ago the same algorithm stayed profitable for about a minute. After that "someone" started guessing your actions and cutting your profit, in few minutes your algorithm would only generate losses, while profiting others.
Initially our program traded with options and futures and most strategies were based on correlation of different goods/markets, a bit later on we had a pool of algorithms running in paralel, with constant reevauluation of profitability of each algorithm. In the end the most profitable algorithms were the ones that acted against all logic and should have generated imense losses in "classic" market. It was all about guessing what others will guess what you will do next and acting against it.
The company ended it's operations 3 years ago since it couldn't keep up with time (By then it was all about latency and proximity to ex datacenters).

We did consider building a high-frequnecy trading datacenter next to ex datacenter but the plan was shelved due to uncertanty what our competitors would do. (HF trading is really simple.. you don't need any complicated algorithms... just wait for any buyer to send an order to market, with market price and huge quantity (near or orver current cap for given level) and since ex will take few ms. to allocate the order you can, within that time place 2 smaller orders one for buying at given price and one for selling at next level. If your quantity is 10% or less of the clients quantity and you can act within 1-2ms (incl. latency) there is a good chanse that your order will be prefered over the larger order...)
