I would be tempted to try USB over a longer
distance.
I believe the main limitation is in the pair of wires feeding the
power. USB has 4 wires +5v, 0v, A & B. A and B are the data pair, as
long as you used a local power supply at the distant end it might work OK.
As I understand it, the actual DATA is carried as a balanced RS485 type
signal so should be good for quite a long distance over
CAT5.
Of course, I could be talking B******* as I have never played with
USB.
I cant test this theory as I dont own any USB
kit.

Excuse the blonde question :-)
but why is their such a limitation on the
length of cable for USB? - do they use very low voltages for their
signalling, and as such this would deteriorate over any distance - say
15 metres?

It just seems such a waste, that I can buy a
reasonable colour web cam for under £50 and I could then have more than
one connected to my pc, that they would all have to be within a few
metres of node Zero!!

yeah, gotcha.

I'm sure I've seen them around, but I've no idea
where. Perhaps someone
else
has?
