Third IDE open/edit Flas directly?

Hi.

I want know if it is possible - in any way - open FLA files (from versions 6 to 8) into an third IDE, edit this file, converting, for example, texts and animations, automating codes wich converts static texts into dynamics, accessing database etc and export a brand new SWF movie.

Is it possible? Because - as far I know - the FLA format is not open source.
I have a costumer that told me about a “miterious” programm wich can do all this things like edit/export - direct from his FLA files - a new SWF or EXE media. And save another FLA file with all those modifications. In other words: is it possible I make my own Flash IDE?

Does anyone know something about it?

Thanks a lot, guys!
