That would be a very good idea. I once tried loading the game "The
Glove" over the cassette port from a portable digital audio player. It
didn't work properly because "The Glove" expects to be able to stop the
tape and then resume loading its level data when it's ready. Adding an
interface for the tape relay would increase compatibility with programs
like "The Glove".
