Use a remote display as a local one
I am not aware of any Linux software that can do that, though there is some commercial OSX and Win software that enables you to use a screen as a second screen for OSX (over the network): http://avatron.com/apps/air-display#downloads

If you are running dualboot Linux/Win this maybe an option.

I use it with my MBP. The connection is fast enough for office, mail, browsing, etc.
