I just ran across the Flex 3 Compiler Module, which by the looks of it seems to be a server side compiler.

Has anyone tried it out or used it for any practical examples? I’m not really finding much about it from Google. 
Adobe says they aren’t going to update it or provide support for it any time soon, but has any freelance group decided to update it with Flex 4?
I can see this being quite handy and time saving for testing purposes.
