I want to connect emesene to msn through the new xmpp service howto

Actually, things are quite simple! [1] And no, before you continue
reading, this is NOT working as you could expect.
After reading this [2] i've seen you don't need to provide a secret
key in order to authenticate with the live xmpp server so i registered
the "emesene" app in windows live and set the "mobile" flag.

If you'd like to try playing a bit with it just grab this emesene
branch [3] and follow the instructions below:

You can now use the client_id i obtained

"client_id": "000000004C070D1E",

in order to do an oauth2-auth with your favourite browser (remember:
this is a quick and dirty howto, it's not meant for everyday msn
users!).
Just navigate to:
https://oauth.live.com/authorize?client_id=000000004C070D1E&redirect_uri=https://oauth.live.com/desktop&response_type=token&scope=wl.messenger
wl.offline_access
(yes, space included..not sure if wl.basic or whatever else is needed
too) and after being prompted for your user/pass you'll see the url
just changed to something like
https://oauth.live.com/desktop#access_token=YOUR_ACCESS_TOKEN&token_type=bearer&expires_in=3600&scope=wl.offline_access%20wl.messenger


Note down the access token thing and run the emesene branch i told you
about before

Now, providing you already have some sort of live id (note: i tried
this only with an @hotmail.com address), say YOUR_USER at whatever.com,
you select msn-xmpp from the service's dropdown menu and put
YOUR_USER at messenger.live.com as user, and the previously-noted-down
long and ugly access_token as password.
Click connect and after a few seconds you shall see some of your
contacts (and some nice exception infinite loop in console, yay)

I included the latest xmpppy available in that branch so it can be
easily tested..but i added a really tiny modification to sasl auth in
order to support msnxmpp's

elif "PLAIN" in mecs:
sasl_data='%s\x00%s\x00%s'%(self.username+'@'+self._owner.Server,self.username,self.password)
node=Node('auth',attrs={'xmlns':NS_SASL,'mechanism':'PLAIN'},payload=[base64.encodestring(sasl_data).replace('\r','').replace('\n','')])
else:

becomes

elif "PLAIN" in mecs:
sasl_data='%s\x00%s\x00%s'%(self.username+'@'+self._owner.Server,self.username,self.password)
node=Node('auth',attrs={'xmlns':NS_SASL,'mechanism':'PLAIN'},payload=[base64.encodestring(sasl_data).replace('\r','').replace('\n','')])
elif "X-MESSENGER-OAUTH2" in mecs:
sasl_data='%s'%(self.password)
node=Node('auth',attrs={'xmlns':NS_SASL,'mechanism':'X-MESSENGER-OAUTH2'},payload=sasl_data)
else:

I don't plan to work on it, i just wanted to see if there was
something that could be done with minimal effort so feel free to try,
improve and why not completely integrate (e.g. in-emesene oauth2 with
some sort of webview, fix xmpppy with msnxmppy etc.) it in upstream
emesene!

I forgot to add: if you'd like to start some xmpp hacking with python,
i asked around and people have been recommending SleekXMPP

website: https://github.com/fritzy/SleekXMPP

real world example usage: http://poezio.eu/en/index.php

if someone is interested you could write an extension just like
"emesene/e3/jabber" and maybe supersede xmpp usage


tl;dr: msn supporting xmpp is really nice, but having it 100% working
is not so easy

Have fun,
