Salesforce.com, which offers enterprise applications as online services, and JotSpot, which develops wiki applications, last week announced a partnership to deliver a suite of collaborative services. The JotSpot Tracker, which lets users share Excel spreadsheets using only a Web browser, will be available as an on-demand application via Salesforce.com's AppExchange. Users will be able to incorporate the Tracker into Salesforce.com deployments. Today, users must exit Sales_force_.com's CRM application to work with spreadsheets for project schedules and contact lists. JotSpot Tracker for salesforce.com is priced at $10 per user.
