Which MacBook models support (directly or indirectly) dual DVI monitors, for a total of three screens? I've read through the "Questions with similar titles", and I don't see anything that directly answers my question.

Which current MacBook models (of any product line) support (directly or indirectly) attaching dual DVI monitors, for a total of three screens?

The monitors are third-party (Acer). By "directly or indirectly", I'm acknowledging that I'll likely have to buy additional cables.
You only have two options, and they're both supported by all current MacBook Pro and MacBook Air models:


Use a DVI splitter to spread a single DVI output across multiple monitors (which will look like a single external monitor to the OS). The maximum resolution for an external monitor on all MacBook Pro or Air models is 2560 x 1600, so your maximum for the split displays will be 1280 x 1600 each (or maybe 2560 x 800).
Use a USB graphics adaptor for the third monitor, which will thus not have hardware graphic acceleration.
