LPC: What's happening with webcams

Program A archives periodic cam snapshots.

Program B does motion analysis.

Program C provides a high-quality stream for the internal LAN.

Program D provides a low-quality stream for Internet access.

Program E does the aforementioned autofocus, auto-brightness, and/or whatever.

Program F monitors that the stream exists, and raises bloody hell if somebody disconnects the camera.

Program G ... you get the idea.

Requiring that all of this be packaged in one single application which does all of it perfectly is (a) unrealistic and (b) not The Unix Way.
