This is a good idea, but I think a bit too limited in the form you
describe. If it's worth doing, it's worth doing in a properly generic
manner. I think a better approach would be to 'annotate' a single MIDI
file with information about the loop points, possibly as a seperate data
structure, or maybe better by using custom controller messages embedded
in the MIDI stream. This would allow a simple intro+loop like you
describe, but would also permit more complicated control flow (eg. play
bars 1-8, repeat bars 9-16 four times, play through to bar 64, and jump
back to bar 9).

Thanks for the suggestion: it's going on the todo list...
