Yeah, all I'm saying is that when there are such large trade-offs
between CPU usage and network traffic requirements, it might be a
good idea to allow a user to choose with some connection option.  For
perspective, just within our organization we have cases where we're
communicating between busy machines on the same 1Gbps switch, and
cases where we're communicating between nearly-idle machines over a
sometimes-saturated 3Mbps WAN connection.  This change would be a big
win for one and could potentially be a big problem in the other.
