Can I distribute the open source SWF compiler with my application?

I'm unclear reading the documentation if there is a difference between Adobe's official Flex SDK, and the open source version?

Can I distribute the open source SWF compiler with my application?

I have a flash application that users can change the fonts being displayed, if they supply the fonts in a compiled SWF. I found I can let the user select a font from their computer system, and using the mxmlc command I can easily generate a SWF with the font, which can be loaded by my application so the font will be part of the run time application when played on systems without that font already in the System fonts.

I was wondering if I could distribute the open source SDK so that I could compile these font SWFs for the user so they would not have to get involved in complicated Flash development. The audience is non Flash audience.

I tried using SWFMill but the fonts don't seem to work as they do with the mxmlc compile.

Thank you,
