It is interesting, but Windows Messenger is not as bad as you can think. PA works with it (4.7, 5.1), but only UDP because of using maddr extension in contacts if using TCP. I think that there is "new" 4.7 release because I have downloaded it about half an year ago and this version was much better than 5.1 downloaded some time before (for example unsubscriptions are done in reasonable way instead of sending lots of messages at the end as done before). It doesn't use PUBLISH (it uses some SOAP call instead), but as soon as will be PA able to do subscriptions to users it will hopefuly work. (PA is prepared for it now, but this code must wait till perfomance issues will be solved). Most clients able to handle presence messages handle them in their own way and have bugs in it, thus Messenger is really not the only one client behaving a bit strange. I'm not sure about version, but I think that 0.9.6 has too old presence modules to be really working. I recommend to use presence snapshot (ftp://ftp.iptel.org/pub/ser/presence) or CVS version. Warning CVS version doesn't correspond with "presence handbook" (text about presence in SER) published on that FTP - some changes oin parameters were done, new XCAP module, ...
