Filed a JIRA for the CXF/inheritance issue:

https://issues.apache.org/jira/browse/OPENEJB-1020 : "Inheritance not  
supported in JAX-WS endpoint interfaces exposed via CXF"

Jon, feel free to grab that one if you want to look into it.

Also filed a jira for interfaces supporting multiple views:

https://issues.apache.org/jira/browse/OPENEJB-1018 : "Support for  
exposing a single interface as @WebService, @Remote, and @Local"
