Stream audio from OSX to Ardour(in Linux)

Is it possible to run OSX VSTs and AU and stream their output to an Ardour Workstation running Linux?

If so, how is it done?

google for netjack

its not trivial to set up (or rather, not trivial to understand how to set it up), but it works very nicely.

On the Netjack page it says:

“This will change, when the packet format has stabilised and NetJack will be part of Jack”

Will Netjack ever be integrated into JACK?
I think the Netjack project is dead. The latest official release is over a year old.

its not dead. its just not actually changing right now. and yes, it will eventually become part of JACK.
