how low-latency?  anyone who cares about latency needs to know the numbers,
and especially versus linux on the same hardware.

is this trivial (to a *ix person) or am I missing the point?
most interconnects provide IP emulation and thus by definition
work as you describe, no?  even the converse (use various interconnects
without recompiling/linking) is also done pretty commonly.
