Doug,

Scali and ParTec also have commercial products that are similar. In
the ParTec case, they interface at a slightly higher level than the
low-level driver, so it works with any ethernet device, not just a
few. Scali is probably similar in this respect.

This approach does give a better 0-byte ping-pong latency than normal
TCP over ethernet.
