I agree with sessions. Even if we ask as a requirement PHP 4.1.0 
minimum, maybe it's better to have the choice of using sessions or not. 
We could look the possibility of using some kind of plugin mechanism for 
passing data.

We currently use blowfish for hiding user name and password in the 
cookies, so we should continue this way with sessions. But other 
sensitive data contained in a query (a social security number, for 
example) may find it's way in session data, so we have to deal with 
this. Encrypt everything? With mcrypt it would not be too bad, without 
mcrypt, ouch.
