if this sort of thing interests you i highly recommend checking out the 
persistence-sig (and its archives) @ python.org, its somewhat dormant now.  
but one of the goals is to define a persistence interface, that different 
persistence implementations can be plugged into... well more or less ;-)

the mounting syntax could be thought of as zope specific i guess, although it 
seems generic enough to me, in a general sense it means mounting a persistent 
object model onto a user's existing one, no different than say importing a 
module to mount that module into your runtime object model. off course maybe 
i've been playing with zope for too long.

/me realizes he is way off topic
