I already saw it on Ajaxian ;)

To be able to host a web based jabber client not bound to any specific
server. Have a look at http://jwchat.org. You can connect to almost any
jabber server from there.

AFAIK there's only my 'JabberHTTPBind' servlet. It's hosted at
http://zeank.in-berlin.de/jhb/. It implements most of the BOSH spec but
not all IIRC. But I'm pretty sure it won't scale up to 20.000 users :D

You'd have to implement XEP-206 XMPP Over BOSH too.

Sorry, you mean a cometd/bayeux transport for XMPP? If so, yes, there
is. Please contact Ian Paterson, author of BOSH and XMPP Over BOSH. He
was working on that topic too (some time ago...).

Definitely ;)
