the few core features of the video seem generally unnecessary. automatic data binding on multiple clients and auto syncing with offline storage is cool- but not really imperative for most apps to get started (which is where tools like this will shine).
that said, the project is obviously young and i obviously know very little about it, so i am interested to see how it develops.
that said, this is a problem many have tried to solve (without writing their own language), and (imho) failed. backbone is (imho) taking the first step in the right direction. to be clear, i am not comparing lunascript to backbone directly. they seem to be two very different solutions for the same problem.
