Well, it seems that if you wait... just long enough, you may just get what you wished for.

I was just finishing my implementation of a scalable push solution for real-time web-based applications when I was asked to review an implementation for a reader of my blog.

The project isn't officially launched yet, but it is to be called Juggernaut (http://juggernaut.rubyforge.org) and it looks really promising. Juggernaut uses Flash and it's sockets implementation to push data from subscribed channels directly into your application.

I will post the review when I've finished doing the load-testing of the server (as much as possible on my limited hardware) and, of course, get the author's permission to do so.
