As Chris has pointed out the standard VIC and RH below 7.3 do not support
USB cameras without a lot of fiddling.  We have run RH 7.3 with OpenMash Vic
and the Logitech Pro 3000 with success, as have others.  I'm not sure what
this effect this combination would have on using the PIG.

Thanks for this. This Logitech 4000 doesn't exactly appear a perfect
candidate. Jim Miller of inSORS sent me a separate mail recommending the
3000 model. I wonder if the 3000 has similar problems to those you
describe...? Jim/anyone?
