Another situation in which this could apply is for migrating from one 
db+model to another... a little modeling mapping code could read from 
one EC and populate another that uses a modified model. This may not be 
the most efficient to way to do this, but possibly the most flexible 
and one that would guarantee data integrity and consistency the most. 
Any opinions on whether this would be a good idea or not?
