I am working on a site now, producing content that can be delivered via MODx, or to an alternate Flash version of the site. I found some great ways to do this using SWiSHmax (see
http://www.swishzone.com/), which can connect directly to a PHP script via URL, but the site I need to connect was already designed in Flash, so... Now, I am anything but a Flash guru, so I’m not yet sure how this will work in Flash itself, but it should be very doable, and I’ll share what I learn once I get a chance to work on it some more, probably later this month.
