This was one of my intentions with trying to prototype
an API for foreign table types in mnesia (included in 
the RDBMS patches). Berkeley DB might be a good 
candidate (others have integrated berkeley_db and 
mnesia already, in a proprietary fashion.)

After discussions with Dan Gudmundsson, we've agreed 
that the approach needs more thought. There may be 
better ways to do it.

With really large tables, the synchronization protocol
between nodes also needs to be looked at.
