It's a singleton. It's not in JNDI.
I understand how you are using JNDI. I am glad you stick to the spec.
As far as providing a proxy through JNDI I can't imagine that it would be too hard:
new InitialContext().lookup("geronimo:/gbeans/<blah>");
What am I missing here?

How does the application get the instance of your class? Or is it a
static method call? There isn't really any way to bind anything not
specified in the j2ee spec into the geronimo java:comp/env jndi
namespace. We've thought about providing a way to get a proxy to any
gbean from jndi but it isn't very clear how to fit this into the j2ee
requirements/plans.

We might add the ability to override reference patterns in the
config.xml. I was thinking you could lie and give your gbean a
j2eeType=JCAManagedConnectionFactory :-)
