Yes (3). When in complete doubt, punt to an octet-stream.

I figure application/x-cave will be enough. People outside NCSA/EVL
probably don't need to think about this particular one, its presence
in the Mosaic code notwithstanding, but the same issue will come up
repeatedly all over the place and the answer should almost always be
an experimental (x-) MIME content subtype.
