No, they are different file formats & libraries, etc.

I don't know.

It would certainly be nice if opendx supported hdf5.

It shouldn't be _too_ hard to fix the type information in hdf4 (I can help
you with that, if you'd like), but it would be _very_ hard to depend on
math/netcdf instead of its own.
