Infinite Session with different users using same app, is it possible?

[GoogleCodeExporter]

Here is my situation, everytime a user gets a new highscore, i wanna send a 
facebook message into my game account, and i've managed to do that with 
infinite session, i've stored the session data with the attributes of my 
account and always connects directly to my profile and posts it.

Now imagine that i want to do the same thing, but with another profile, is it 
possible to user the same application? Any ideas how would i identify the 
different accounts before logging in?

I think the only way you'd be able to do that sort of thing is if you coupled 
the sessions with keys that the user could input. The only thing that makes 
most sense to use as a key is users usernames, however storing that off may 
violate Facebook's policies (http://developers.facebook.com/policy/). So I 
don't think there a way to distinguish between accounts elegantly on the same 
computer - you might as well just let the user re-login every time (it's what 
they're use to with every other application anyhow :) ).
