21.5" iMac thunderbolt - video in?

[TSE]

Has anyone used the new 2011 21.5" iMac's thunderbolt port and can confirm that it does indeed have video in just like the 27"? Some people have told me it does, others have said no.

Everything I have read says it does not support it.

Thunderbolt is bi-directional by definition, so with the right hardware, it'll be possible. Video in, though, is not the same as Apple's Target Display Mode.
