Sure: http://habahaba.im/

Actually, this is just a Jappix fork with some extra features. You can
take a small description of the project here: http://jawiki.ru/Eng:HabaHaba

For the moment, habahaba doesn't actually use jslix, it mostly inherits
jappix code. (except of server side part which was rewritten in python
and uses twilix).

I started to write jslix because I want to implement jingle in habahaba
using webrtc protocol (for now there's only voice support using Flash
and without jslix and written by another developer).

Unfortunately, I realized that existent libraries are too bad to write
fast and flexible things (moreover, they are written in bad js, both
jsjac and strophe, so my aim is to get rid from them but for now jslix
needs them as a transport layer) so I decided to write the same thing
I've already done for python and twilix: some simplified XML schema in
declarative style which will be used to parse, build and validate XML. I
have also dispatcher which can handle queries and catch exceptions and
represent XMPP errors as language level exceptions. It most interesting
in python because it has a generators support, so the work with XMPP
became too easy just as work with synchronous protocols:

query = SomeQuery()
iq = Iq(to='somenode at someserver', type_='get')
iq.link(query)
try:
    result = yield dispatcher.send(iq)
except FeatureNotImplementedException:
    alert('Client does not support this feature')
else:
    print result.some_result

twilix has some problems which need some refactoring because but it's
almost useful, I have several services written and working on that.
