I think that http://www.zopelabs.com/cookbook/1003271138 can be modified
to do what I want.  I will know later today.

Very distasteful.  Then I might see that I was working with the "foo
adatper" when the "bar adapter" was really processing it, and
acquisition could even disguise the fact.  Ouch!

Thanks.  The context I was in was so bizarre that I hope no one else
needs this.  (I have a home-brew UserFolder that holds a connectionID, 
I wanted to change it over to another DA without deleting and
re-installing the UserFolder.)

Anyway, on the off chance that anyone else will ever need something 
like this, I did an external method, whose guts was:

self.acl_users.connection_id=self.this().aq_acquire('Bar_database_connection')


See, easy!  (Actually, it was...)

Thanks again.
