I just posted over on the SWX blog about some recent updates with the project. If you have been wondering what has happened with SWX since the blog was last updated a few months ago, go check out this post.
Highlights include a solution to using the current AS2 version of SWX within AS3 projects, and SWX being featured in a chapter of the new Friends of Ed book entitled "The Essential Guide to Open Source Flash Development", written by me!
I will also be posting more about this on the SWX blog in the coming days, but I am starting an initiative to form a development team for an AS3 version. If you are interested in helping out with writing the necessary byte code, have started something similar on your own, or would like to help out in some other way, please post to the SWX mailing list.
