In particular, using it to control MS Windows clients?

I'm trying to achieve an affect similiar to what Stardock's Multiplicity app does, only with a PC and a Mac. (Multiplicity has planned OS X support, but none is available yet)

I've read that this can be done with osx2x, but docs and tuts are hard to come by.

I knew what the reply was before I clicked, I'm psychic!!

Using osx2x and RealVNC, I've gotten my Mac and PC running side by side, and I can switch control between them as if I were using a multi-display system. I just move the mouse onto the display of the PC I want to control. On the fly switching with a VNC session being opened transparently in the background. This totally kicks ass.

Now if only osx2x didn't put a STUPID big ass red arrow on the screen of the mac when I'm on another display.

Also the caps lock doesn't seem to pass through...

Does this mean you're doing half as much work on two machines, or a quarter of the work mre efficiently?

Simon -

Since I'm still getting used to having only one screen on my PC, time will tell. I think that overall I'll be more efficient since now I can run my Mac and PC stuff concurrently, as if they were both on the same system. There's no time cost for swapping monitors.

Multiplicity, once available for Mac, will make this even easier, because then the machines will share a clipboard and drag and drop works across displays.
