If you use separate bundles for each set of pairs, you could also
switch to copper-FDDI, in case 100BaseT does not make it in the market
place or spends the usual decades battling The Standards Process.  CDDI
is closer to standardization than 100BaseT.

CDDI will be faster than 100BaseT for most stations for the next few
years, because FDDI uses 4KByte packets.  The smaller 1500 byte packets
of 100BaseT are significant at 100Mbit/sec speeds for the current and
immediatly forthcoming generations of high performance workstations.
For example, DEC was not quite able to show 100Mbit/sec with
TCP/IP/FDDI on their Alphas in their Interop92 booth.
