Is it worth me building my own local App Inventor?

Yesterday or late last night at any rate Google announced that they were releasing the code for their Android App Inventor product. You can download it here. Now I’m considering whether I should attempt to compile and run it locally myself.

It sounds like a kind of cool project to try out, but almost certainly one that will cause lots of problems for me. I’ll let you know if I can make it work, or even if I try.
