100m of Cat5e is about 60 quid, Cat6 is 80. That's a small enough difference that I would opt for Cat6 because it is quite possible that I would want to switch to 10 gig within the lifetime of the cabling.
I wouldn't run more than a few ethernet cables in a trunk, I would site a switch on each floor.
You can run 10Gbe over Cat5e up to 55 meters, not that I've tried it, only ever used it over fibre.
F*** me. Things have come on a long way since I last poked about in the physical layer.

If you know what cable's going in there, best to put it in along with the conduit.
Well, many thanks for the replies - fair bit to think about!
