[erlang-questions] Mnesia, versioning and recovering from network splits

Folks,

I think there's a reasonably straightforward way for Mnesia to recover  
from network splits. I also think that it would be much faster to  
merge databases in this scenario than drop a database and reload it  
form backups.

I believe merging databases would require versioning of Mnesia records  
(simple integer should do) and the addition of a merging mechanism.  
Record versions would be shipped around and the latest version of the  
record would then be pulled by the server that has fallen behind.

What are the flaws in my thinking?

	Thanks, Joel
