The only consideration that I cared about was: Are these shares related
to a particular user or are they 'globally' shared?  My answer was that
they are globally shared and therefore no specific access permissions
needed to be setup.

I'd lend you my copy but I refer to it at least once a week so I really
don't want to do without it.  You could check the libraries too - they
may well have a copy and the price is right!

If you were the only one that could change it then that would work.  But
if you are the only one that can change it - why not just have the DB on
the memory stick in the first place?
If you aren't the only one that can change it then you need to figure
out how to merge changes and detect and arbitrate conflicts.

I think this is a bigger problem than you may realize - most apps do not
have provision for merge/de-conflict of import data.  The ones that do
tend to be PIM like where it's routine to 'sync' a device against your
computer.
