Not in my case. I don't allow more than one user to edit an object at the
same time. I'd need to have some sort of conflict resolution to support
paralel editing (like user1 changes variable A and user2 changes variable
B - if they both commit both changes should be preserverd) - this looks
like a difficult thing to get right, and not really worth the effort. What
the user does in one session with forked browsers is their problem :-).

As I see it, what having multiple sessions buys me now is that other users
(those who don't edit) don't see the edited values until they are
commited. I think this effect could be achieved in other ways too.
