Is there any community module available for Instant messaging in Odoo 7?

After searching, I found 2 sites:
1. https://bitbucket.org/anybox/web_im. **
2. http://febru.soluvas.com/2013/09/how-to-activate-instant-messaging-on.html  -- This works for me, but does not start CRON jobs.

** Cannot start the web_socketio server.py (WITHOUT BUILDOUT)
Traceback (most recent call last):
  File "/opt/openerp/v7.0/web/addons/web_socketio/server.py", line 3, in <module>
    from openerp.addons.web_socketio.web_socketio import SocketIO
ImportError: No module named web_socketio.web_socketio

Steps done:
1. downloaded the necessary packages using hg clone
2. copied those files and pasted it at WEB/ADDONS
3. installed dependent module at Odoo 7
4. tried to start using python web_socketio/web_socketio/server.py -d mydb.
