Not quite good enough, I'm afraid.  I might have many menus that
reference that, and others out there in gopherspace might also
reference it.  While I'd be able to control my own usage (albeit with
some difficulty), I have no control over how others out there link to
it.

Well, let's get back to this point.  I'm not sure that you must cache
it.  Assuming that a robot will traverse an entire server at once (am
I wrong with that assumption?), it would involve only one extra
request to ask for robots.txt before traversal.  If, OTOH, servers are
hit in a more random pattern, I can see there would be a problem.

Is it practical to cache this data then?  I might be inclined to
suggest that it is.  Given that only a few of the gopher servers out
there are both actively maintained and have a situation warranting
this sort of treatment, perhaps it is not so problematic a situation
after all?
