is it possible to have a virtual ethernet midi device seen by rosegarden, so that rosegarden can play midi files and send the midi notes via tcp/ip to another pc on the network?

to describe a bit more on 2 pcs:
- 1 pc with ubuntu 8.10 and rosegarden playing midi files on a ethernet midi port
- 1 pc with ubuntu or xp with an ethernet midi port connected to the 1st pc receiving the midi data and generating visuals

thanks for your help
