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
