I use a program called 'motion' to track movement and take snaps. I use
it for a camera I installed outside of my garage door, for various
reasons (knowing when someone pulls up, had some problems with vandalism
on that side of the house).
The up side is that motion is very tuneable, senstivity, limiting snaps
per second and such things. The down side is that it's highly cpu
intensive, eats about 95% on any machine I've run it on, although I've
currently dedicated a p166 to that effort.

xawtv-remote is a good effort here, or streamer. Both come with xawtv
as I recall. xawtv-remote requires xawtv to be running to get a snap.
You can get a single snap with streamer without xawtv running.

wintv here, works excellent.

I don't know how you would view the same 'window' on different clients
at the same time, if that's what you're asking. I have viewed xawtv for
my driveway-cam on that machine and now on another, using standard X
solutions.

I didn't have to buy my radio from a specific company to listen
to FM, why doesn't that apply to the Internet (anymore...)?
