you can use a zope3 global utility for all methods.
Your connection can be in /a volatile/ attribute.

Using SQLAlchemy through some integration layer like zope.sqlalchemy
or z3c.sqlalchemy is fairly easy, well understood and supported.
I strongly recommend using such a mainstream solution instead of baking
your own integration layer for yet-another-ORM unless you are skilled
enough and having all the necessary Zope background (e.g. integration
of third-party backend systems with the Zope transaction system).
