All sounds good to me.  When can you have that done?  Only thing I can
see is that this to me assumes that all the keys for a given namespace
would be on one server, and yeah, it would be kind of nice if a
namespace could be distributed.

There's a chance I could actually brush up my C a bit and write a
solution, but I have no desire to write it and then not applied to
trunk.
