I've got 4 lengths of reasonable quality speaker cable (~2 pounds per
metre)
in some oval trunking from Wickes (that will just about take 2 x 2.5mm
cables). These are wide and flatish, and go from a double metal box up into
the ceiling where they split to each corner.  It was quite difficult to get
all 4 lengths in originally - I had to ensure they weren't twisted and
didn't overlap.  Getting them out and back I think is not liekly to be
possible.

One of the circuits from http://www.epanorama.net that I found
transmits IR
over the coax - so that would seem to be a better option.  Just need to
give
some thought about how actually to implement everything now (with as little
apparent disruption as possible).
