I swear, you guys are such buzzkills some days.  I was suggesting a 
model for building easy prototypes, and advocating a more formal way to 
explain, in what could be code form, what someone means when they 
suggest a particular quorum model or the like.  Maybe all that will ever 
be exposed into a production server are the best of the hand-written 
implementations, and the scary "try your prototype here" hook only shows 
up in debug builds, or never gets written at all.  I did comment that I 
expected faster built-in implementations to be the primary way these 
would be handled.
From what Heikki said, it sounds like the main thing I was didn't 
remember is to include some timestamp information to allow rules based 
on that information too.
