plonegears

Plonegears tries to make plone run offline. Still very early days.

Current release

No stable release available yet.

If you are interested in getting the source code of this project, you can get it from the code repository.

Google Gears is an open source browser extension that lets developers create web applications that can run offline.

CSS, JS, skin images and some kupu resources are cached offline.

Clicking the 'Take Offline' button will cache the pages linked by the content tabs.

No idea how to support KSS yet.

Cache searchable text in the offline sqllite database and plumb in an offline search widget
Make minimal changes to KSS/kupu to store a json object in the sqllite database when you make a change offline. (Perhaps disable KSS initially)
Move the offline button into a portlet. Portlet can serve to show status too.
Make it work for unauthenticated users, should be fairly simple.
Could be used as just a local cache to increase user perceptions of interactivity. Just create a manifest of links that they might follow.
