Hi, this is an early announcement of Crossbar.io, a new application server based on Twisted and Autobahn. Crossbar.io is an open-source application router that allows to build distributed systems out of application components which are loosely coupled and communicate in (soft) real-time. README: https://github.com/crossbario/crossbar#crossbario At it's core, an application router provides generic routing of both calls (for remote procedure calls) and events (for publish & subscribe) which is realized via WAMP, an open WebSocket based communication protocol. Why WAMP?: http://wamp.ws/why/ Technically, Crossbar.io has a multi-process architecture with controller and worker processes, which lets use scale up on multi-core. We also prepared things to add scale-out on multi-node. We've got some early encouraging feedback from developers who think Crossbar.io might get the next Django, MeteorJS or Vert.x: A developer guest post: http://tavendo.com/blog/post/is-crossbar-the-future-of-python-web-apps/ Crossbar.io is an open-source project, and still in the very beginning. Rough edges, stuff breaks, moving fast. If you want to give it a try: https://github.com/crossbario/crossbar/wiki#quick-start We are looking for feedback, help and contributors. It's a big shot project, and to make it take off, we need core hackers and grow a developer community. I know, sounds bold. Sure, and it is. In any case, I'd love to see the Python community get even more ambitious. We can't let the J's of this world take over;) Cheers, /Tobias
