Midi controller into Cubase from slave computer

Hi guys, my Cubase 6.5.5 is on a Windows 8 box, now, and this OS doesn’t support my Roland GI-20 midi driver for my guitar. I have a ‘slave’ box running VSL VEP5 into Cubase, on Windows 7, which does support my GI-20. Is there any way to get Cubase to communicate with this other computer so that I can record my midi guitar with it? In other words, can I set up my GI-20 on the Windows 7 box and have Cubase on the Windows 8 box read it so I can record with it?

Thanks very much.
