In short:
Check out the MUTT subsection of this page. There you’ll find a simple todo/issue application I wrote for my company (Irian Solutions) to test some offline patterns. The resulting Dojo Offline example application is publicly available now.
More detailed:
Yesterday I held a presentation about offline web applications at the AjaxInAction conference in Frankfurt/Germany. It was called “Offline-Webanwendungen mit Google Gears” which translated would be something like “Offline-Web-Applications with Google Gears” and was all about Google Gears, Dojo Offline and a practical example application. For this purpose I was allowed to publish an example application I wrote for my company to test some offline patterns - MUTT.
MUTT stands for MultiUserTodoTable and is a simple implementation of a todo/issue tracker. Simple only, because of the sychronisation and the server part have been kept simple (e.g. you can’t edit anything but the status of an issue - which makes synchronisation easy). But beside its simplified functionality it offers a full blown implementation of a data switch, shows templating with Google Trimpath JavaScript Templates and shows how to deal with Dojo Offline (Events, ActionLog, …).
You can find MUTT in the open.source section of my homepage, or you directly follow this link.
So have fun with the example application - and let me know if anybody liked it 
P.S.: The slides of my presentation are available here (german!).
