...then you'll be interested in our open source project over at jtrix.org. We're building a platform for all kinds of adaptive and highly decentralised systems. You can buy in external services for your application, including hosting, so your apps can grow organically across the Net as needed.

Unlike Anthill we're addressing a wider variety of needs (in fact, any kind of app you want to scale up), so you can build all kinds of things on top of Jtrix, from traditional P2P (Freenet, Gnutella, etc) to other apps needing scaling and security (Web-based mail, Passport-a-like, and so on).

We've been at it 18 months now and have things like an HTTP server and servlet engine which work in this environment. It's great to see these kind of frameworks growing in popularity.
