Most VisAD file adpters (extend open the
entire file, but there are some that do not.  You could
write an HDF-5 adapter whose open() method would create its
own little GUI in a JFrame to ask the user which part of a
file they want to open.  We haven't done this, so there may
be some little problem I don't foresee, but my first guess
is that it will work.
