RFC: DBIx::ETL or DBIx::replicate

I've got a collection of scripts, modules, code snippets that I'm
considering turning into a module. It would be an ETL type of module.
Basically, you specify two data sources, one as the source and the
second as the destination. Then, you can specify updates from one to
the other. You could specify synchronization of the two data sources.
Generate the SQL for the updates to happen. Generate the SQL for the
table to be created into the destination data source. And, last but
not least allow the user to create a method(s) to handle massaging of
data the the row level or at the field level before inserting.

Your comments are welcome.

Thanks.
