Hi Wade,
A couple of comments.
1.) In your gadget you probably want to wrap gadgets.rpc.call in a
function passed to gadgets.util.registerOnLoadHandler to make sure the
gadget is completely initialized before making that rpc call.
2.) In your container I would suggest you use the container feature.
It takes care of some of the nasty stuff with regards to registering
RPC callback functions. All you then have to do is call
container.rpcRegister('initial_gadget_message', _messageHandler)
