I've just received an interesting email from Jaromir Sivic, a czech developer who sent me news about a project of his called 'Radical Flash Chat'.
While I haven't tried myself yet, Jaromir describes it as a framework that enables PHP and ASP.NET developers to build and manage their own Video Chats, Flash Chats and other multimedia videconferencing applications easily in a very short amount of time. The configuration screen certainly looks quite promising, listing both Wowza and Red5 as a Media server option. There's also an online demo that you can try (that's if it is online, which seems to be fairly intermittent).
I encourage you to try Jaromir's product and share your feedback with him, or indeed below in the comments.
I'm happy to post any news about similar projects or other news items, just drop me an email.

The chat program looks great!
Some minors:
* it's not possible to save chat transscripts
* you can see only 1 camera at a time
