Good question....

I would say that one the may problem is that jack MIDI does not has the 
concept of time-stamps in the "future" . The Jack MIDI "events" are 
received in real-time (similar to what MidiShare does with the Receive 
callback concepts) but have also to be delivered in real-time.
In the absence of any scheduling mechanism,  I don't think the 
MidiShare API could be re-built on top of the underlying Jack MIDI 
buffer transports system.
