I meant virtual desktops, mostly because I like to be able to take my laptop anywhere. I actually used Synergy at one point for my desktop setup (and also because the OSX mouse acceleration profile was broken for me for quite some time).

A cool hardware project might be to take a micro Linux ARM board with LVDS display output, mount it inside the CD bay in my laptop and make an internal LVDS switch to quickly switch between OSX and the Linux board. That would be pretty much ideal. :)

I wonder if it'd be possible to provide a virtual display to a small ARM board and embed it into a window, so that you'd have the virtualization effects (two OSes on one machine) without the speed loss

I think it's possible do to so, I remember seeing this ARM USB/HDMI board, which apparently can mirror the screen over USB: http://www.fxitech.com/technology/any-screen-ip/

Not sure how well it works, though.
