... You have that point-of-failure anyway if you are using the RAM-based sessions provided by Zope's core sessioning. If availability is important to you, then you *need* to be using ZEO and a load balancer, at which point you also have to look at a more scalable / available sessioning solution.
We are using ZEO, a load balancer and nevertheless have sessions in RAM. True, it is less safe than with persistent sessions -- but it is also more efficient. We do this by ensuring that independent of the load balancer's choice a request for a given session goes to that Zope instance that has this session. -- Dieter
