I have been using DotGNU on my MacOSX to run .Net programs I wrote long back.
You can write, compile and run .Net programs on GNU/Linux, MacOSX and other platforms.
Great effort by Gopal and the team on this project. Thanks guys.
BTW! Mike has allowed me to post the updated code (some new features I added). Thanks Mike.
BTW! It would be great of FlashDevelop can be run on MacOSX using DotGNU. I read somewhere, someone has already managed to run SharpDevelop, so I feel, I can try running FlashDevelop. Thanks Arul for suggesting this.
update: I think, I am able to run FlashCommand using DotGNU
