I have seen several exploits of people adding 1 or 2 serial ports to the WRT54G. Does anyone know whether it would be possible to add a USB port to allow either connecting more storate or other external devices such as a webcam. I think that it would be neat to build a wireless webcam for under $100 based on the WRT54G plus a cheap webcam. Presumably one would use the included webserver plus a hacked version of the firmware. Anybody know if this is possible?
