I've done some searching and found that it seems to be possible to forward X11 apps to a mac machine over ssh (i.e. ssh-ing into a linux box and launching an X11 app and having it show up on the mac's display).
What I'm wondering is if this can be done in reverse (i.e. ssh-ing into a mac machine and launching an app and having it show up on a linux display). If this is possible, how do I go about setting it up, and more importantly which OS X apps will this work for?
