can anyone offer hints of pci-express performance?  for instance,
boards like:

have a x16 PCI-e slot, which afaikt, would be a perfect place to put
a low-latency cluster interconnect board.  I haven't heard Quadrics
or Myri talking about their roadmap for PCI-e, but IB people seem to 
think it'll give them the throne.  hard to see why, since it'll 
help their competitors as well.  come to think of it, if IB people 
claim PCI-e will shave over 1 us off their latency, what will PCI-e
do for Quadrics (already under 2 us!)?

thanks, mark hahn.
