Not in conduit, by any chance? Oh well :-(

Should work, but you might have problems.

Have a look at http://www.epanorama.net. IR is
_basically_ very simple.
Maplin sell little IR receivers, which produce a demodulated data stream.
Use that at the other end to drive a 555-based multivibrator, everything at
38kHz. It would be easiest to run a second cable with the co-ax - like
some exterior-rated 'phone cable. Such a repeater, to run on cat-5, is
high on my to-do list, now that most rooms are getting wired for sound...
