Macbook Video Output (DVI)- Is it possible to produce two outputs?

Here's something that may work:

The type of switch you need is rather expensive since it has to handle two DVI outputs from one DVI input and be able to switch between them.

See this site for an example of prices:

You may get lucky and find something less expensive. VGA switches are much less expensive. If both your external monitors can handle a VGA input, all you would need then is a simple VGA switch box and a DVI to VGA adaptor. You can buy the mini DVI to VGA adaptor from Apple for $19.00.

I've used this with my MBP; not sure how the 1920x1080 external res output of the MB would work/be affected.
