Great news: our buddy Paul Kulchenko just added Moai SDK support to ZeroBrane Studio! ZeroBrane Studio is a slick IDE for Lua and Lua-based frameworks that supports full debugging, watches and stack view. I took it for a test drive over the weekend and was really impressed.

Check out Paul's screencast for a demo of Moai support and the project links:

It's pretty nifty.
