At the present time, we don't expect to have the time to work on that
until some time after a first release. The focus right now is client side.
Assuming that works (I'm not sure how to deal with the size limitations of
cookies exactly), the main feature that really needs server side storage
is some types of logout.

Speaking personally, I'm deeply skeptical of most clustering/replication
technologies. I'm not a fan of asynchronous "best effort" replication, and
most other types aren't very robust. I would be more comfortable with that
for something like logout, that has no hope of being reliable anyway, than
for mainline features like attribute queries.

We're not comfortable making any firm commitments at this stage of the
process, but that is the general thinking right now. That's reflected by
what's associated with the 3.0 version in Jira.
