Webcam-server is absolutely the easiest way to show on the net what is seen from your webcam, the software is very stable (I’ve just installed Ubuntu, and shows the date 2004) is based on Java and to make it work is enough to give these commands:
#> aptitude install webcam-server
#> export LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so
Now point your browser at localhost:8888 and see a snapshot of that seen from the webcam.
