Thanks for this recommendation.  I'm inclined to agree.  Do you have
any indication that such boards might be available with a fast PCI
slot for Gigabit ethernet?  The frustrating item for us appears to be
the apparent mandatory tradeoff between memory and network bandwidths
in the currently available motherboards.  (I.e. to get a fast PCI
slot, one apparently needs a dual xeon board which will split 3.2 Gb/s
memory bandwidth between (possibly) 2 cpus -- to get 4.2 Gb/s or
higher memory bandwidth per cpu, one needs a single cpu board with
either RAMBUS or dual channel DDR which invariably seem to have only
PCI 33Mhz/32bit slots.)

Take care,
