Or… just wait for Teleport, which can send its signals between multiple vst-instances. That way you just open a separate instance on a new track with a teleport-receiver and a midi-out. I don’t know when it will be ready, but I read somewhere that this was the behaviour of teleport in an early 2.0 beta-build.
Edit: Here we go: Teleport - Strangest discovery of Rack VST so far....
