People have indeed put many things (some strange) into the Ogg format. I was once contracted to build MIDI + Vorbis support and I added a mapping for MIDI in Ogg fairly easily. Granted, I was heavily involved with Xiph, but I am not Monty. It took a little digging and one or two questions I'm sure, but it wasn't rocket science. The end result worked spectacularly well.
