Here's the kind of meter we typically provide for commercial building applications:
http://www.electricitymetering.com/p3894/veris_h8036_enercept.php
That's just the retail cost of the meter.. add the cost of the web appliance (Honeywell/Tridium) with I/O module or Lonworks/modbus interface, plus labor to the electrician for wiring/installation, graphics design, programming the appliance and commissioning the whole enchilada. Not cheap.
I had over a dozen Optiplex GX280 machines plagued by this issue. These had been purchased in mid-to-late 2005, and began to fail in early 2007. Dell extended the warranty on all of the machines affected by the bad capacitors, I got a free replacement board for every one of these.
I work for a controls contractor doing primarily HVAC, central plants, and lighting control in large commercial buildings.
The commercial market has changed quite a bit over the last few years, with Tridium leading the way with its qnx-based embedded controllers featuring the niagara-AX framework, adopted by the majority of the big players (Honeywell, Siemens, Johnson Controls, Distech, etc.) http://www.tridium.com/partners
Tridium (now owned by Honeywell) has been developing the Sedona Framework - combining 802.15.4 and IPv6 - as an open source project:

However, this stuff isn't priced for the home automation market.
For those interested in the DIY @home stuff, check out www.iobridge.com/store for some cool web-based i/o control products. They also have an interface to your X-10 modules for less than 20 bucks.
If your area is served by AT&T, ask for a dry-loop DSL line. it's the same thing, just no dial-tone on the line. I just got the Elite (up to 6Mbps down/ 768Kbps up) for 35.00 a month.
Have you heard of Tridium? Their JACE box (sold though various OEMs - Honeywell, Siemens, JCI, etc., and authorized contractors) can take care of the control and the web UI very well. Then all you need is a handheld device with wi-fi to reach a web page for control functions. bias alert: I work in commercial building automation controls and I am certified in the Niagara-AX Framework.
No building controls system runs on Windows. The front-end software is there to provide a GUI for interacting with the system.
Scheduling, data collection and trending, reporting, etc. The logic runs at the controller level, be it application specific controllers or freely programmable.
If the front end goes down, the worst that will happen is you stop collecting data on your trends. Tridium's supervisory controllers run a JVM on QNX. (www.tridium.com) Their front-end runs on Windows or Linux (Red Hat support only at this time)
I work in the HVAC/Building Automation/Energy Management field and can tell you that the application of the future is Automated demand response. One of our customers is now signed up on a program with SCE. On set days during the summer months when energy demand is expected to go higher than normal, we receive a signal over the Internet to a box with an integrated relay. Upon receiving this signal our web-based EMS system initiates a sequence for demand response by shutting off lighting circuits, as well as shifting cooling setpoints up by 3 degrees during a 6 hour period. The whole idea is to reduce peak demand usage.
I don't see any of this reaching the residential consumer anytime soon.

This is a great industry to be in, specially now with everyone going "Green" and energy prices going up. However, you need to understand A/C, Electrical, and IT. Control systems have come a long way.
Scenario #1:
A citizen of Brazil decides to come to the U.S. for educational purposes. He needs a passport, student visa, proof of financial responsibility, proof of ties with his country, etc. He is to return to his country after his studies are completed.
Scenario #2:
The citizen above wants to bring his dog pupi (10 yr old schnauzer) along with him. The dog doesn't need a passport or a visa, gets a cheaper airfare ($200 as opposed to $1,458), and on top of it, free permanent residence and/or citizenship. The only requirement was for the Brazilian government to provide proof of vaccinacions taken by the dog.

checkout the Wattnode. This device does a lot for the money. There are many different configuration options, and plenty of technical info on their site. http://www.ccontrolsys.com/products/pulse_output.html datasheet: http://www.ccontrolsys.com/downloads/Data_Sheet_WNB_Pulse.pdf checkout the application notes as well: http://www.ccontrolsys.com/support/app_notes.html

This is about as cheap as it gets for a DIY project. If I were to give you a quote for a commercial grade version you'd shoot me in the eye. http://www.iobridge.net/projects/category/projects/ http://www.iobridge.net/projects/2009/01/real-time-power-monitoring-system/
