I think that absolutely yes. Any code contribution is very welcome. Because it's a separate addon you can simply create a patch in jira and attach files. We can also make it more visible in the wiki then. For formal things I think that you need to sign contributor agreement on jboss.org site. If you are interested in users interest you should ask in User Forum - Design Forum may not be checked by everyone, but I know that time to time there are questions about integration with SSO frameworks. So I understand that you mean providing implementation of - LoginModule (JAAS) - UserModule - RolesModule I assume that you are using JB 2.4?
