for a DAL (abstraction layer), this is tied to _one_ persistence store
(the string method was not).
The good part of this (from a programmer's perspective) is that it is
explicit - you know "StingListProperty" is intended to be a gae thing;
The bad part: it erodes the concept of portability, the prime goal of
DAL ...
It may be useful for the moment, but there is a design tension which
is begging for a more comfortable resolution ...

Perhaps you can say a little more on "... and you can make your
own."?
