You n00bs!! Just kidding...
Nullsoft (Streaming|S as in Soft) Video will record from a web cam to a file. It is open sorce too so you should be able to write some code to embed it into CF.
And if you have your cell phone internet dialup working, then this software will stream your web cam via shoutcast to a winamp client.

download the NVS tools...

after you install, open NVS Live Capture > chose your web cam in the Devises drop down > then goto File > Set capture destination > pick "File". It will save it in NVS format that can be played back with Winamp

To stream your web cam you will need to down load the ShoutCast DNAS Server.You can run the server software from your home PC if you always have a way to know the ip address, i.e. the no-ip.com trick or static
I have not tryed this and there could be port issues streaming over a GPRS provider. shoutcast uses port 8000 and 8001 by default but can be adjusted.
let me know if you have questions and I will try to help.
now I am just going to have to go try this and see if I can get it to work while driving on the highway.
