Thanks for that clarification.

In assessing the feasibility of such a plan, one might do well to
factor in that luminaries like Bill Bumgarner have warned that Core
Data sharing is never going to work very well even in ideal

Therefore, its hard to justify any engineering effort at all that
results in a shared SQLite store.

Thanks again for the useful pointer -- it may well save the day.
And, I like watching videos :)
