That's something else I'm curious about. The GPU power that would be needed. I'm talking anywhere from 23" to 42" screens. Obviously that's a large range, but I'm curious what would work.

I think that's kind of debatable. My laptop can output to a 32in TV, so then it could probably handle two smaller monitors (2 x 19in?).
I feel like its my duty to clear this up. The screen size of the display is NOT a factor when it comes to the processing power that the GPU needs. For all the GPU cares, the display could be a 9001" TV, or it could be a 0.005pico" display. Its the resolution that counts. In terms of graphics horsepower needed, a 0.005pico" display @ 1080p needs the same power as a 9001" TV @ 1080p. Nothing more, nothing less.
Regarding this topic, as long as the laptop has the ability to slip the output into two different channels, there is no way to do it. Unless, you buy the EVGA usb thingamabobby or similar. A normal laptop is quite capable of powering two displays if all you're doing is word processing/browsing. Don't expect to game on two displays though.
Word is, there is an external PCI slot that can accept a modern GPU. The extention plugs into your laptop's express card slot (assuming you have one), two which you could then plug in a GPU. That way, you can have an actual dual display setup, while still using your laptop as a third screen. Where to buy one: http://www.hwtools.net/adapter/PE4H.html
Scroll through to find one that works for your system. A word of caution - its still an engineering sample of sorts. It'll work, but its not an elegant solution.
