I have an old logitech webcam and tried connecting via USB to the alix.

I have seen (on other threads) that people have been using Internet Protocol cameras to good effect. Is this the best way to go? Can they work "plug n play"? Or do they need drivers installed remotely? The IP camera I last looked at, had ethernet connection - but given that the Alix is already using the only ethernet socket, how/where should/could it be installed?
Any help would be greatly appreciated.
