Really.  I didn't get that far with my 802.11b ad-hoc network with 11
segments.  Even with NO load, segments kept dropping out for a minute
or two or three before rejoining.  If I recall correctly, each of my
11 laptops was its own segment and I was using multicast between them.
When all the machines were joined, the application worked well, but
machines dropped out for several minutes so often, that I had to give
up on the whole effort.
