Hi Erik, Your LocationAwareClientMessageBus actually fixes an existing problem we have only partially addressed so far: Setting the remote bus endpoint programatically (see https://issues.jboss.org/browse/ERRAI-380). So, I think we could even add this to the ClientMessageBusImpl directly and default to getApplicationRoot() if no custom Configuration was found. Wdyt? Making gwt-phonegap a dependency of errai-cordova sounds fine to me. Example setups and demos could also live under errai-cordova/demos. That's how we set it up for errai-bus/errai-cdi/ etc. Cheers, Christian
