I've been talking about a new gateway interface for a while in the forum. I will release more details and the source code soon.
This content will be updated and improved on the dedicated Moteino Gateway page where all the source code and details will be published as they become available.
This is a work in progress and I encourage discussion, suggestions, bug reporting in the dedicated forum I created for this and all gateway related topics.
UPDATE: code has been posted: http://lowpowerlab.com/gateway/#sourcecode
Here are some more screenshots:
