Hi, I am currently writing my bachelor thesis about performance measurings concerning XMPP. One chapter will deal with the simulation of user (clients) behavior. Due to this fact I would like to know if someone of you is aware of statistics or other approaches that cover the behavior of XMPP clients in real XMPP environments. Probably there are simulation programs that already implement XMPP users for stress testing purposes (except for "tsung" - I am not very familiar with erlang :)) ?! I would be very grateful for your information! Thanks in advance!    - Matthias
