Here is great a article on building offline salesforce apps. Yes, you heard it right, offline salesforce apps!
Imagine your Salesforce.com web application user meets a client at a coffee shop, flips open their laptop, and notices that there’s no internet connection. This
doesn’t stop them connecting to your Salesforce.com web application and
viewing account and contact information though, much to their client’s
obvious surprise. With the use of Google Gears and Google Web Toolkit you now can make any
on-demand application work offline. Read all about it in this
article and download the sample code to get started.
Also, this year, we have Google in the breakout sessions and the Dev Lounge at Developers@Dreamforce ’07. It is not too late to join us.
