Can I daisy chain multiple displays with Thunderbolt?
Currently the port on the MacBook Pro is both a DisplayPort and a Thunderbolt port. The limitation, as already explained in the other question, is only relevant to DisplayPort, which has to be the last device in the chain, if daisy chained. 

So in short, and in theory, it should work. According to the Thunderbolt page, you can plug in any adapter for DisplayPort and it should work, as long as the device also supports it.

The only time this gets really complex, is when you need to both power the device and use it using just the one port. If the device has external power, it shouldn't cause any major problems daisy chaining, however, the DisplayPort device still needs the last device in the chain. Simply because it cannot transfer data at the speed and rate the Thunderbolt can.
