resynchronizing mnesia nodes

We are looking at various policies for recovering from communication
failure with mnesia, and studying Chapter 6 of the Mnesia User's
Guide, Version 4.0.

Suppose you have several nodes running mnesia, replicating content.
They become partitioned long enough to record mutual mnesia_down
entries, and continue to receive updates.
 
In some special cases - for example, when updates to a table consist
only of adding a positive increment to a counter, or of inserting a
record with a globally unique key - it should be possible to
resynchronize automatically without fear of inconsistencies.
 
Is this sort of thing readily feasible with mnesia?
Is anyone doing it?
