mnesia cluster limits

We have been arguing amongst ourselves as to the advisability of
creating a cluster of between 20 and 100 OTP nodes, all running
mnesia, all with the same erlang and mnesia cookies. Individual tables
would be replicated sparsely, only where needed.

What is the overhead of a full mesh of n mnesia nodes, not counting
replicated transactions? At what point does it become prohibitive?


P.S.: I was just at the Erlang workshop at PLI2002, but foolishly
forgot to ask the above question of the experts. The workshop
was quite informative, and more fun than a barrel of monkeys.
