gmPG2 does not care how you acquire the auth tokens, for one
thing. It can also use any DB-API compliant connection
anywhere the <link_obj> parameter is supported in gmPG2.

There currently is no built-in support for injecting
established connections into gmPG2 for later transparent
re-use.

This would be possible by making gmPG2 have a pool of
connections and adding an inject_connection() method. Again,
I'd be happy to see suggestions as to how to add pooling
capabilities to gmPG2.

Sort of, yes, in that they all call
gmPG2.run_ro/rw_queries() with link_obj=None.

No.
