Broadcast routing/repeating (was: ICMP Redirects)

... I think you'll regret doing what your thinking of
You'll end up wasting gobs of BW with broadcasts. Also *nix hosts
designed to connect to ethernet are a little "generous" with their
broadcasts - because the BW of ethernet is so large.

You can accomplish most things by careful subnetting, but I'd like to hear
of any exceptions...
