As in, have two copies of MusicBee running simultaneously on two different PCs, with one sending commands to the other?
Short answer: no.
Long answer: no, and it sounds like a nightmare to get working, so I wouldn't expect to see that sort of functionality any time soon.
It might be easier to look at installing a screen-sharing/remote access program on the headless PC so you can operate that version of MusicBee directly on your other PC.
Bee excellent to each other...
