I've been creamed before. With your UID as low as it is i'd figure you've been flamed before for a negative opinion on Apple or MS.

Very well written. I only wanted to make one, trivial comment - an OS cannot possibly allow an email program to directly change the latency of interrupt handlers (your DPC latency remark). This implies that a userland program can somehow change the behavior of the kernel and hardware significantly, which either cannot or should not be the case.
As tiny as that statement is, especially mixed in with a sea of insightful, poignant insight I found the juxtaposition of your knowledge with that one remark vexing.
I don't use windows, but I would be tempted to check against Outlook next time I'm in the office
When are the Windows folks going to get to the desperation phase?

I'm lucky I was able to do so, but I jumped the Windows ship entirely mid-Vista era. Before I get flamed to death, I'm only speaking for my perspective, here.
For me, I can spend mental resources on several things: learning new technologies, making things work, development, etc. The key point is those resources are finite. Having done Windows administration since NT, I can tell you from past experience and from where the Redmond train is headed you will always be re-learning how to do the same things. Damn near everything I learned in linux with Redhat Valhalla still applies or is just slightly different now, in 2012. What has changed is me. Because of the time I have spent honing my skill with an OS whose skills tend to carry over, I have an entire corporate network that I can easily manage, with comfort knowing there will always be a distro, mine or someone elses, I will be able to get work done in. From a software persepective, I'm really happy I didn't spend a bunch of mental resources learning Silverlight/.NET whatever and put the time into learning Scala, Python bunch other exciting techs that are Free to do what I want with, not just MS. I don't want career lock-in, essentially.
Just my 2 cents, we'll see if my bet continues to pay off.
You need to really be concerned about the following:
1.) Provisioning the equipment. I don't know how "small" a small office is, but this is going to spiral out of control quickly if you don't have an elegant way to setup handsets and make changes.
2.) Your change from circuit switched to packets. There are a lot of discussion points here, but the biggest you need to be aware of is latency is king. You might have a really slick p2p setup with OpenSWAN on 2 high bandwidth, cheap DSL or cable connections, but the jitter will kill you.
3.) How does your voice come in? If you are under contract and you have a PRI or some TDM circuit, you have to consider how you will interface that, and the cards you will need, or the SIP gateway you'll buy are not cheap.
4.) Who is going to manage the call routes, system secuity. I'm well versed with Asterisk, and you'll not find an all inclusive interface unless you go the Digium SwitchVOX route. If you don't pay close attention to security up front, you will experience toll fraud pronto.
5.) Handset support. What are you going to do for replacement parts, who is going to setup all the buttons, etc.
6.) Codecs. Some of the best are not free, i.e. G729. Just about any handset you get will support G711, but 12 bits of fidelity at 64k/sec each way (plur overheard for UDP/RTP) is not that great.
7.) Voice prompts, auto attendants, voicemail, etc.
8.) Status/BLF lights on phones. There isn't really a standardized way to do this, but SIP's Subscribe/Notify is used by some, I think Aastra.
9.) Key system habits. You won't be able to "pick up Line 2".
If I haven't scared you out of it yet, Aastra and Snom make excellent, RFC 3261 compliant handsets, Asterisk is a lot better than it used to be, and there are some alterntives you might find interesting like FreeSwitch or YXA.
Good luck.
Nice sig line. I'd say I thought of it first, but your uid says otherwise
If we are going off anecdotal evidence, I consult with several companies hiring H1B and I only see 30k/year salaries being offered. I call BS on your unqualified implied generalization.
OpenNebula. We have a large install base where I work, it does a fine job. It's essentially a lightweight management layer over libvirt and KVM for us, although it works with other hypervisors as well.
Hey man, when I talk I use AM pressure waves with a low modulation index
So it's just manchester code with a significant DC bias.

This is not a salt - that is an IV. They are not the same.

This is just and ad for trend micro.
I'm talking about reality, not your model. At no point did I or the grandfather's post define limits or a 'probability space' (I think you mean possibility frontier).
Either way, you are arguing outside my *defined* 'argument space'.
You forgot the calculation of the lunar wayneshaft when subleading the uncertainty. Day one shit, bro.
