1. Being able to take the browser offline. Using HTML5 Web Storage to locally cache data. Similar to what many mobile apps do (like GMail). Then you don't have to maintain a persistent data connection. Problems with invalidation and new data. Would probably require entitybroker feeds to exist and UI's to be rewritten in javascript.
2. A working back button.
   • On both Android and iPhone the back button is even more important than the browser. It bacically undoes whatever the last action was, whether that is removing a dialog box, going back to the last screen. Incorporating consistant back button behavior into mobile navigation would be great.
3. Supported integration for conferencing/chat tools, link them up to classrooms.
   • It seems ilke big blue button is getting the most support, it would be great to be able to switch to that and use it. This is quite a ways down the road though because of the lack of Flash on iPhone/iPod, and the HTML5 spec support for cameras being a little ways off.
4. Push notification to phones.
   • Android (and I believe iPhone) support pushing notifications to the phones rather than polling.
     • In Android 2.2 (mostly unreleased) it's by a "Cloud to Device" messaging API that seems really nice. [5]
     • This seems like something we'd really like to take advantage of. Facebook/Twitter/Gmail and others all push notifications and I'm addicted.
       • For example, notification on a new announcements in any course, or a new file uploaded. Perhaps configure how you want mobile push notifications as well.
       • This might be something more to think about for Sakai 3. I think this will be even more important in 3-5 years.
