I'm sorry, I was being really terse when I talked about "sequential
transparency". What I meant was that if client A does a "GET x; UPDATE
y; GET x" that the second "GET x" properly reflects the changes made
by "UPDATE y"; however, if client B does "GET x", even at a time AFTER
the "UPDATE y" happened, client B might see the original data.

If what you want is "sequential transparency" then you don't need to
deal with totally unrelated processes, you only have to deal with a
single process (client A) which potentially might switch between one
proxy and and another.
