Not that I'm urging anyone to do this, nor implying that I have this 
setup running in a mission-critical application.  But I've tested it, 
and it works surprisingly well.

I get my Internet wirelessly, and my CPE is in a room that is guarded by 
a $70 USB camera attached to a PC running the OS motion software 
package.  I actually have three of them in the house.

When they're armed and detecting motion, anything that sets of detection 
in any of the three cameras causes three things to happen: first, it 
immediately begins to capture an MPG movie of whatever caused the 
motion.  Second, it trims off the first few frames of that movie and 
uploads them (via my wireless) to an upstream caching server.  Last, it 
spawns a VoIP call over the wireless to a series of sites where I (or my 
designates) can immediately grab a browser window and (securely) start 
watching the action on the offending camera in real time.

Not counting the infrastructure behind me (e.g. the wireless ISP 
infrastructure beyond my house) the total cost of this setup is about 
$125/camera.

I demoed a junior version of this setup at VON a couple of weeks ago.  I 
live out in BFE where it isn't very likely I will ever have to worry 
about people breaking and entering, much less someone sophisticated 
enough to figure all of this out as he approaches the house to rob me. 
The wireless CPE has a UPS on it that will run for about two hours, so 
even if the burgulator had enough smarts to snip the phone and electric 
wires on the way in, the system would still warn me.

FWIW.
