Autoform with Autosaving?

Hey all,

we currently have autosaving as a feature in our app (a la Google Docs). We are using custom built form components and an internal saving mechanism built around keyups, etc. that is working well. We are spending a lot of time on validations, however, and looking at autoform.

Just wondering if anyone has built successful form/document editors around the autosave functionality built in to autoform? Examples/code would be amazing =)
