Why this. I was told some time ago we should use BDBMinimalStorage to 
fix the conflict problems.

There is no difference between BDB Storage and Filestorage regarding 
the conflicts.

The bottom line is that there is no way of getting an shared session 
running. Why isnīt there an implementation of temporary storage for ZEO 
I dont care about conflit resolution. Its only session data. I simply 
need a shared session storage. But as Far as i can see the is no way 
of doing this. Are we the only site out there running Plone2 (Placeless
transaltion Service) at that scale. How do others handle there Session
