It is a very good idea to support multi-linguality. Would it be possible
to have URIs that explicitly specify the language, e.g.
http://server/servlet/jetspeed/portal/group/sales/SalesCenter/fr_FR ?
Accepting this and returning the language specified in the request would
allow implementing portals where users can select the language and e.g.
bookmark a page in a certain language.
Problems might occur if user's change their language settings in the
browser. This way, the user might apparently loose customizations he
made to a language specific page.

Good !

Do you mean "authorized" or "authenticated" ?

Would this both be permanent cookies ? I guess the cookies would only
contain some identifier that would be used to associate the user with
data stored on the server, is that correct ?

Perhaps it may even be removed. Is there a reason to only deprecate it ?

Sounds very interesting. I'm curious about this one.
