I took the sdk for a spin this last week and enjoyed working with it. I am both a professional and indy game publisher. The key missing element for me at least is the ability to run within a browser plugin. Key to this feature I would need the ability to pass variable information to the plugin from html code. I would love to port one of my games but the ability to run in a browser is a huge stumbling block for me.

Sorry I guess I should have posted that to feature requests but am unable to move it now.

Webpopups allow you to intercept hyperlink click events but thats it so far.

If someone at Corona was interested, there is a way to use Lua in Flash.

I worked on a project called lua-alchemy that ported the lua interpreter to Flash. Actually runs the lua C code in alchemy. Unfortunately Adobe has pretty much abandoned alchemy so I stopped working on it. Some have used lua-alchemy for games I think:
