I think that half the problem with the audio/MIDI over LAN thing is that it has to work with loads of plugs and loads of different systems. With only one player to worry about it could well be less of a problem. Don't forget that VSL came up with the "run outside the DAW" memory dodge years before Logic/Apple did, so they are obviously thinking outside the box. I'm pretty sure that if/when MIR arrives, all controls will be available form the DAW machine, as it would be rather a retrograde step to have to deal with multiple rodents, keyboards and monitors.
