Does a simple netcat transfer go fast enough?  In other words, can
normal TCP in a simple case do the job?

If not, would you be better off "talking" ethernet?  Presumably you do
not need the routing capabilities of TCP.  As I understand it, your
client and server are on the same LAN.

I don't know if this is helpful.  Without knowing the timings from basic
test cases, it's hard to know where to find the best point of attack.
