To quote the beginning of the "What about my web app?" section
This ten step tutorial shows how a client can interact with Hookbox.
Adding web app integration is also trivial.
I can tell you, combining a real-time component with your existing web app framework is not trivial; hopefully Hookbox might change this. In general, a framework that eases this pain is very needed.I experimented with these ideas with my project "Hotdot" (http://github.com/clemesha/hotdot), which is mostly a "big example", not a framework or whatever.
Hotdot uses Orbited (which was originally authored by Michael Carter, and who is also the author of Hookbox). Michael did contact me with the Hookbox project a while back, and it looks as though he has made significant progress on the project since.
This includes support for streams, long-polling, and short-polling. Like everything else in NOLOH, this comes out of the box for all browsers.
A dedicated comet section will be added to noloh.com later in the summer with more examples, demos, and whitepapers.
