Meebo.com Clone

Projects related to XMPP on the web. The flagship project is a
web-based IM client similar to (but not affiliated with) Meebo. An
online demo can be found on our main domain at Soashable - Open Source, Web Based Instant Messaging Platform.

"Soashable"
is the flagship project in the Soashable family. It is the core
application that all other members support. It was originally developed
as a proof of concept over the course of a weekend, and now serves as a
test-bed and driver of technology to support it.

Xmpp4Js
Xmpp4Js
was originally derived from the Soashable code base and is now a
stand-alone project which can be used by anyone who wants to
XMPP-enable a web application.

It is a BOSH client directly comparable to JSJaC,
which is another quality Javascript BOSH library worth looking into.
One key difference is that Xmpp4Js supports Alternative Script Syntax
which allows for cross-domain usage.

Robot Olympics
Robot Olympics is a Spim (IM Spam) fighting plugin for Openfire that is loosely based on XEP-0158 and XEP-0159. It watches for tell-tale signs of abusive activity and subjects clients to an accessible Text Captcha logic puzzle. Future plans include properly implementing the XMPP extensions.
