I imagine a easier solution.  Use a random number generator in both
sides, with the same seed.  Then use a slower way to send "packets
re-sync" that will contain the delta from the generated number, to the
real actual number.

I suppose this speeds are needed for some "fast speed transaction",
that are leeching money from the background noise on the market.

This is not like the Roman empire, where you could make a lot of money
buying wheat wen theres a dry year in egypt.

note: I could be wrong.
