Please tell me why are you considering /tmp as the only one solution? Moving runtime temporary files that do not *have* to be shared from /tmp to eg. ~/tmp is pretty good solution, as well. Unfortunately, this won't solve numerous problems of programs that are not following mk*temp() convention, creating eg. pid-based temporary files ;) On the other hand, most of context pseudo-filesystem / redirection solutions (like making real location of /tmp entries for every UID different) might broke eg. X server / clients functionality etc.
I am displeased with ~/tmp, because I believe constructing a reliable ~/tmp scrubber would be problematic. Consider: what if most, but not all, of the home directories a machine sees are NFS mounted? What if the NFS server is down when you try to check ~/tmp to see if it is local? What if the NFS server doesn't have a ~/tmp scrubber, and it might be a pain to provide one?
