Hmm... you don't believe the use cases and info on how mutation events 
are being used that Dave and I have posted and you don't have any 
alternatives.  Perhaps the conservative solution is do nothing.

You might ask Prof. Jan Vitek if his infrastructure can give you any 
information on mutation event uses.  He may also other ways to get such
