At Williams we are installing 75ohm coax for video when we renovate dorms. We
are not using cable that contains twisted pair in the sheath and I wouldn't
recomend that. If at some point in the future you want to rip out the coax (it
takes up a lot of space) you'll probably want to leave the TP. We are putting
in Category 5 Twisted Pair cable to allow possible future high speed networking
although we don't plan to support more than 10-Base-T ethernet for the
reasonably forseeable future. I would suspect that when video moves away from
coax it will be transportable on the twisted pair along with data. (That is to
say: it IS data!) I don't foresee the need for fiber to the rooms since
bandwidth over copper seems to be increasing to keep up with the demand. (Who
would have thought we'd see 100MB/Sec over copper?)
Of course this is just my opinion. :^)
