I never thought about using a Matrox splitter before, but they have what they call a TripleHead2Go. It's made specifically for laptops with support for an external display, yet it acts as 3 external displays. I'm not sure how exactly it works, but I can see no reason for this not to work on an iMac, MacBook, or MacBook Pro.
It comes at a hefty price (approx. $300), but it sure seems like a good idea to me.
Matrox TripleHead2Go: $309.95

I guess you treat the unit as one display but with 3 times the horizontal resoltuion of one of the monitors and it does the splitting for you, So if each monitor was 1024x768*, you would drive the unit as if it was a monitor of 3072x768 - I guess the iMac could probably do this with sufficent video RAM (allow 4 bytes per pixel R, G, B and alpha), but you might need to to use a special utility for custom resolutions such as switchres.
* I know this is a bit low nowadays, but just an easy example

The downside is that it's VGA only... the same thing in DVI would be much more interesting (and undoubtedly more expensive/complicated).

Yeah, VGA isn't that bad though. I'm using an external VGA and to be honest, I can't notice a difference between it and my iMac screen.
