 Thank you Scott as always!
Well, we want to "cluster" (load balancing, round robin) the Apache httpd RP (reverse proxy) nodes, since SP tights to the RP, it needs to be clustered with shared storageservice.

That would be entirely up to the memcache library.

I already verified that the code doesn't care if it can't update the timestamp, so it's generally irrelevant for it to fail in that spot as long as it doesn't hang.

It is also, almost invariably, pointless to cluster the SP.
