Hi !
I would always prefer a UDP based solutions,  because TCP can really mess up the timing. UDP packetloss usually is below 1%. The bigger problem in this case are WIFI connections, scrambled packet orders and jitter.
Are there any objections to using Open Sound Control based solutions?
To me it makes more sence, because it is an IP-based protocol (32 bit) in contrast to MIDI, which is designed for 8 bit serial interfaces.
A basic MIDI OSC gateway is available here:
Further more, you could use it to control OSC enabled applications like Ardour and provide some customized control mappings.
I wanted to start some extension development on this myself for the public internet (unicast).
Perhaps we can align some effort on this?
I already did a specialized Sysex gateway with OSC which is absolutly relyable. (Remote control of two Yamaha mixing desks).
