I think that a better approach would be to handle it in the level below 
the objectmanager.

Ie. write a product that saves itself as an object in the zodb, and then 
gets its persistent values from the database.

Ie. if you save the sql rows key in the Zope object, you could get the 
row from that key, and then get the column values and save them in 
volatile attributes. (starting with '_v_')

Meaning that one object is one row.

That way it would act just like an ordinary zope product, and can be 
catalogued etc. in Zope.
