1. Would it work?

Hi James,
All the various spec libraries are in the maven repository here:
http://repo2.maven.org/maven2/org/apache/geronimo/specs/
In terms of starting with Swing and eventually going to GWT/Servlet,
you could still use EJB in either case. In the Swing setup you could
embed the EJB container in your Swing app, then when you deploy to
Geronimo you can use the EJB container there.
Here are some examples of embeddable EJB container usage:
http://openejb.apache.org/examples.html
Note those are test cases, but the concept applies equally to any
plain java environment. Also note that this very Embeddable EJB
Container concept is being added to the EJB 3.1 specification itself.
Theoretically, you should be able to design with the final
architecture in mind from the start and share the same "backend"
between the Swing and Web GUIs.
Hope that helps!
