Keyboard cable too short

In v7n83, Mike Sokolo(v) (sokolov%media-lab.media.mit.edu) asks about
keyboard extenders. We wanted to do the same thing (put the workstation
pedestals in another room) for our 3/260C and decided just to buy the Sun
50' extender kit (part # CBL-KYB-50FT), for about US$200.00. When it came,
it was just a cable; no active components. It was sheilded, however, and
required a new connector piece to be soldered (!) onto the keyboard
circuit board to connect the shield to. The hardest part of the job was
finding a torx screwdriver.
Unshielded cable should have greater distance than shielded, so I'd be
optimistic that 100' would work. I'm pretty sure that the signals are
just rs-232, which we all know goes a lot further than the 50' it's spec'd
for.
We just used RG59 for the video, with no ill effects, even with the TAAC.
