Disclaimer: I know little about the varying license issues.

Regarding alsa MIDI:
I'm primarily concerned about having an "-Ma" capability for the XO 
platform.

Is it possible to do something specifically (and perhaps uniquely) for the 
XO? (Would this make any difference to licensing concerns?)

Such a module could well be a separate downloadable (optional) upgrade just 
for people who needed "-Ma" capability (i.e., those wanting to do this sort 
of "musical Collaboration").

As long as the upgrade would be simple to do on the OLPC, separate 
distribution would make some sense.

For example, in my OLPC work/documentation, I'd simply include 
download/installation instructions for the module, should users want to do 
collaborative realizations of my Activities.

Hi,

Yes, but only on the 5.10 manual. I've just updated the online manual
at csounds.com:

http://www.csounds.com/manual/html/index.html

I've also had a look at alsa midi and the sources are there and it's
actually not hard, but those sources are GPL, not LGPL. I would have
to rewrite the whole thing from the ALSA docs, which would not be
pleasant or create a new GPL module for alsa MIDI which I'm not sure
it's a good idea either, since it would have to be distributed
separately...

Any ideas?

Cheers,
Andrés
