Hmmm.... Cisco isn't the only provider of IB cables.  Last I understood, 
they buy theirs from others.

Cisco does appear to be transitioning to *other* technologies.  Again, 
they aren't the only IB provider out there (seems such a shame, gobbling 
up TopSpin and then effectively discarding them).

Qlogic, Voltaire, Mellanox are happy to sell you stuff.  You can even 
call some of the tier2+ players and they will help.
