Yes, do the conduit if you ever plan on re-wiring, and remember to leave
the nylon twine in the conduit (i.e. pull more twine with each cable pull).

There is a company that delivers tested cable that can out-perform
standard Category 5 cable:  Berk-Tek, LANmark-350 cable.  They claim
their cable  delivers 18dB ACR @ 100 MHz, and has been tested to 350
MHz, which they suggest might be good enough for 622 Mbps ATM (OC-12
equivalent!).  I don't know if it's plenum rated Teflon covered, or not.

Black Box *may* be reselling this cable, or they may be imitating it.
