I took the last two weeks of 2011 off work. During that time, I ported Correspondence to Windows 8, published HoneyDo List for Windows Phone, and submitted an entry for the First Apps contest. Here is a demo of HoneyDo List running on a Windows 8 table that Chris Rajczi generously loaned me.
HoneyDo List uses Zebra Crossing to generate and recognize QR codes. These codes contain a unique ID to which both devices can publish and subscribe.
The tablet publishes all of its lists to the ID, and subscribes for updates. The phone, upon scanning the ID, subscribes to receive all of the tablet’s lists, and then publishes the ones that the user selects.
This two-way collaboration continues after the lists are exchanged. Both devices subscribe to the shared lists. New tasks published on one device will be received on the other.
It is my hope that the story of Correspondence – synchronizing facts among all your devices via publish/subscribe – will align with the story of Windows 8 – access to all of your applications and data wherever you happen to be. If so, I expect this to be the start of an exciting opportunity.
