Couldn't this be generalized a little bit? Can't we assume, for
example, that the HTTP service is _always_ either on port 80, or on
some port >1024?

Similarly, gopher is _always_ either on port 79 or on some port >1024.

This rules out the gopher: hack to access finger info. I won't loose
any sleep over that. A finger: URL should probably be deployed, along
with gateway interim solutions.
