@Emkeyen - This is an XSLT extension (it should work with any XSLT processor), and thus will work if you install it directly in your Inkscape extension directory. I still have to finish clipping, text and gradients. I'll post it here as soon as it's a bit more usable.
Of course, your help is welcome. Since I'm not an Adobe user, I can't test with Illustrator, Flash builder or anything else (except if I find an easy way to test it with the open-source Flash SDK on Ubuntu). My only help is currently the FXG specification (which is not always very clear...) and http://fxgeditor.7jigen.net/ (but there are some bugs). I'm also going to test Wonderfl (http://wonderfl.net/), but it doesn't look straightforward.
