mnesia table events (see Mnesia User Guide, section 5.7.2) get you the ability to trap and process every record update, with old and new record data provided.

The only slight issue I have with this is that transaction boundaries don't show as seperate events; for my application (echoing changes to a derived copy of a table) means that I'm now looking at doing this in application instead.
