WebSphere OSGi Application Model

As noted previously, WebSphere Application Server's alpha support for OSGi applications is similar to that of SpringSource dm Server. Now IBM's open source server, Geronimo, has taken its first steps to join the party.

Apparently Geronimo 3.0 is now based on OSGi, like all other modern Java app servers. (I wonder what vestigial traces of its GBean/XBean heritage remain?)

Geronimo's OSGi application model is provided by the Aries incubator, so I wonder if that is also the base of the WAS alpha, since Geronimo is essentially WAS CE.

Maybe the answer is that the closed source WAS is also based on Aries, but I didn't dare accept the license agreement on the download to find out.
