The flip side oft his is that it can be quite difficult to build complex 
  queries without deep structural knowledge of the database (and they 
are therefore somewhat fragile).  However, we're working on that.  A 
somewhat unsettling thing about using atop is you start to realize how 
incredibly inefficient some of the things that are really easy to say 
with SQL are, even in SQL DBs ;).

If an operation is synchronous in atop, it's fast. Right now this means, 
"if it's easy" - but a more advanced query mechanism will fix this.  If 
you have any ideas, please let me know.
