Btw. how do you handle running status? I guess you are talking about 
connections made by JACK or ALSA MIDI, so you don't need a MIDI merge 
box and you don't have to take care because of the running status? Note 
that the MIDI spec was made to connect hardware devices too. I'm not 
sure if you need to take care of the MIDI spec, maybe JACK and ALSA will 
smooth away difficulties for you. I don't program for Linux, but did it 
for hardware devices.
