just an idea, not sure it would work correctly: create a second account 
which mailboxes are folders of the "normal" account.

an alternative (not what you want, but may be related), if the user has 
few folders, create one POP3 account per folder. This would allow a user 
to see two specific folders if he connects with a "small device".
