I'd be very concerned if you had a lot of machines running on the same 
side of a hardware switch and all were "nodes"... they'd replicate all 
the broadcast frames and n^2 plus the hardware switch's contribution :). 
Sounds like a problem for machines that are reasonably close together 
and/or large implementations of these.

Kind of cool otherwise.
