Well, RMON does that, but it uses its own filtering language, and if we
want true Ethereal display filters, then, of course RMON is out (unless we
were to create a private filter MIB, I suppose...).  I just thought
interoperability might be useful.  I'm not convinced RMON is better than
your proposal, BTW, I just wanted to offer the thought.

We discussed this in 1999/2000 so you might want to check the archives for
that discussion, too.
