Thunderbolt, the new Apple/Intel connector replacing DisplayPort,
is a bus rather than a single connection and in theory allows
daisy-chaining external monitors.

Right now there are laptops with Thunderbolt but A) graphics drivers
haven't been updated to handle daisy chaining and B) monitors don't
have the extra "pass-through" ports either. I've also seen back of
the envelope calculations saying there's not enough bandwidth for
more than one HDTV res monitor on a single connector anyway.

Maybe in 6 months?
