To paraphrase Mitra, I think we can step back and look at the big
picture. I assume from what you wrote that you agree in principle to the
information being there you are just concerned about the syntax? If that
is so then we're all in agreement. As agreed, we will need to include
metainfo when necessary for a particular access method. In this case FTP
requires it so we're basically working on what goes where. We could try
to make this look like gopher somehow, but I'd prefer to to step in front
of the careening gopher-type train (no offense Mark :-). (Can trains
"careen" ? :-).

Having said all of this, we just need a workable FTP url which
incorporates the "typing" data in such a way that (a) we don't break (if
possible) existing FTP-URL parsers (b) it conforms to the legal character
set (c) is unambigous in syntax. Correct?
