With Charlie Wood's Spanning Salesforce sales professionals can subscribe to personalized, secure RSS feeds and keep on top of theri most important information-including leads, opportunities, contacts, activities, and documents-on your PC, Mac, or mobile device.

Here's the Salesforce.com AppExchange listing and Charlie gives a great introduction to how it all works here.

You need an RSS reader that supports secure feeds. For Outlook users Spanning Partners recommends Attensa for Outlook 1.1 (thanks Charlie) Spanning Salesforce lets you track your new and updated information in Salesforce.com using RSS using RSS. And since Spanning Salesforce doesn't require adminsistrative privleges, any individual can sign up.

When information is added or changed in your Salesforce.com account, you'll see it reflected in your Spanning Salesforce feeds. If a new lead is assigned to you, you'll see it in the My Unread Leads feed. As leads become opportunities, you'll be able to track changes in your pipeline. If you're responsible for customer support, you'll be notified of case and escalation assignments.

Plus, as new documents are uploaded you'll get not only a notification but also the ability to download any new document with one click. In fact, with your RSS reader properly configured, new documents will be automatically downloaded as they become available.

I like this quote from Paul Greenberg, CRM guru and author of CRM at the speed of light..."any Salesforce user...would be stupid to be without."
