Yes, it's strange to help people with their questions about tomcat,
ejb3 and geronimo on glassfish mailing list ;-)

Yes, easier than you might've ever thought. Just use OpenEJB with
Tomcat and you don't have to bother yourself with Geronimo or even
GlassFish. You just deploy your ejbs with glassfish descriptors (if
you've got them) and these ejbs should run without any changes on
Tomcat. All the Glassfish descriptors are 100% supported. Still can't
believe it's true - just give it a shot or better read about openejb
and its features before you follow the route -

Geronimo bundles OpenEJB as its EJB container and as such you should
not expect troubles with your approach. Send your questions to
Geronimo or OpenEJB user mailing lists. See
http://geronimo.apache.org
or
http://openejb.apache.org.
