displaylink, using your ppc as a seconday monitor

[mrspeedmaster]

I just broke down and ordered a 7" MIMO usb displaylink monitor. I wanted a 3rd monitor just for my photoshop palettes (macbook, 20" and now a mimo).

I remember a while back, you could use a pocket pc as a secondary monitor with software. Unfortunately, I use mostly OS X and linux. I rarely boot into windows.

Is there a way to make a PPC device (HTC Touch Pro or any PPC device) as a displaylink type monitor?
Or maybe, is there a way to run VNC as a virtual display and simply have the PPC connect to the virtual display and pseudo monitor spanning?

Reason I am asking because I have so many extra PPC devices not being used. E.G. Dell Axim x51v w/ wm6.1 and a VX6800 Verizon. I would love to use those. Right now my Dell Axim is just reloading facebook/tweeter on a dock.
