Somebody already did - IB Objects has a feature called "DMLCache" which
does just this, even across application boundaries. You have to set up
both triggers and events for it. Apart from that, IBO has a lot of synchro
and refresh options that would make anything like your "reverse query" a
right royal pain in the butt.

Of course, the everfresh_dataset is a dataset that is inside a READ
COMMITTED transaction... I think most c/s programmers care *a lot* about
any "feature" that was stuffing data across the wire that we didn't ask for.

just my 0.002 cents worth
