(1) what does "immutable" mean?
(2) do you still feel that the result set id should be assigned by the server?
(3) is the ttl just a "hint" or is it stronger than that? I infered from one of
Matthew's messages that he thinks that a server is morally bound to keep the
result set available for at least approximately the ttl period (and of course
morally bound doesn't mean legally bound).
