Topic: Gaikai PS3 and PS Vita interaction

Anybody know if there are limited games that can interact between PS3 and PS Vita using Gaikai? I hope this isn't an earlier question to that possibility.

Not sure what you're asking. Gaikai is cloud-based service designed to stream games from a central server network to a variert of Sony platforms. We don't know much more than that yet.

There is no Gaikai for PS3 or Vita.
I think maybe what you're looking for would be the LittleBig Planet 2 Cross-Controller DLC

Or do you mean remote play? There's very few games that support it, but the list includes God of War (1 and 2), ICO, and Shadow of the Colossus.
