there are fewer infiniband-only chipsets out there than there used to be. most ib hardware is actually a "converged" network adapter, which means you can also do ethernet. it's interesting to do a line count on some of the linux drivers. they tend toward many tens of kloc. you just haven't lived till you've taken a peek at a 50kloc driver. it may be that a reasonable ethernet or tcp/ib driver could be written. - erik
