assuming a reasonable mapping (i.e. the m2m example in the
datamapping docs)
session.query(Node).select(and_(
nodes.c.id.in_(select([group_nodes.c.node_id],
group_nodes.c.group_id==1, correlate=False),
nodes.c.id.in_(select([group_nodes.c.node_id],
group_nodes.c.group_id==2, correlate=False))
))
the query would probably be better expressed as a couple of JOINs to
aliases of the group_nodes table instead of using IN
