It's time to get moving on this...
I've set up a Basecamp account so that anyone who is interested in putting together a WordPress-meets-Flash CMS can get involved, and start talking about the best way to make it happen!
Although the specifics of how it would work aren't defined yet, I'd basically love to see a WordPress extension that let you manage the text content of a Flash website. It would allow anyone with basic WordPress and Flash skills to hook the two together, without any complex coding.
So... support for static pages, and also posts to allow for blog-style or news sections which were archived, searchable, and maybe even had an rss feed into the bargain.
If you would like to get onboard to discuss the idea further, email me (3stripe[AT]gmail.com), and I'll set you up with a login.
Look forward to hearing from ya!
