Oops, sorry about that - I did have a look at the code, but then was cut off 
the internet for about a week (fiber cable broke in the neighbourhood)...
...and forgot to answer.

Contrary to what I had in mind, the MIDI code in JACK is not a separate 
module, but is driven by the ALSA audio backend. Means we'd have to somehow 
drive it from the OSS backend in our case. Also the MIDI code is not too well 
structured nor documented, and it's hard to tell the exact timing requirements 
to drive it.

So instead of creating a lot of work and maintenance Frankenstein'ing the OSS 
backend with the ALSA MIDI code, I suppose our efforts are better spent on 
ease of setup for a2jmidid and documentation.

Sorry again for the delay.
