I'm Julian Tenney, I work at the University of Nottingham and have been the lead developer on the Xerte project for the last 9 years. Our goals have been very similar to yours in the development of Xerte Online Toolkits, which is now used all over the world and has loads of users / community of developers. I'm not sure how similar it is to the ideas you have for Adapt. The last year or so we've been moving away from Flash and towards HTML5, and this has gone down extremely well with our users, which are mostly educational institutions: I think you may be more interested in the commercial sector?
Anyway, we share the same problem, so I thought I'd say Hi,
