I don't think so. I don't see any functional reactive stuff in Luna, whereas that's the whole point of Flapjax...<p>Edit: reading more closely, I see why you say that -- "incremental computing" link makes me think of FRP a little bit. But these people's goal with Lunascript seems to be automatic communication between the client and server. The "incremental" part is sending only what's needed to the client to execute the client-side code, which is a really cool idea, but not very much like FRP, I think.
