That's not totally correct. Sessions are (by default) stored in
web2py/applications/appname/sessions/... as files. They are pickled
Python Session objects. You can store these in a database instead of
files using the session.connect(db=SQLDB(<connectstringhere>)) command.
This has the advantage of better concurrency (with the exception of
SQLite which has worse concurrency).
But if you don't use the session.connect command at all, web2py will
just use files for you and all will be ok.
The only thing I store in my session is identity information...
session.userid = "351001"
session.username = "bob"
session.ip = "192.168.0.26"
Once you set those options, you should always be able to refer to them
in your code (as long as the user doesn't delete his/her cookies).

Now that's kinda cool. Fran you should put that on the wiki.
