Oh. Most of *my* FTP URLs come from mail messages where people say
'this is available for anonymous FTP at this place', and I hand
translate it to a URL. Usually, if the file isn't a 'standard' format,
they'll say what it is.

I kind of like the first one:
gopher:path.net//aaa/bbb/ccc:type=image/gif:size=100k

I think we probably need MIME types for things that don't have types
now, like naming a list of items:
directory/ftp directory/gopher
has this already been proposed? I don't see it in the MIME docs:
text/html
and probably things that don't really fit as types of 'data' but
should be registered, like:
telnet/vt100 telnet/mud
