Salesforce.com Launches Web-based Add Marketplace.

This article reports that Salesforce.com Inc. (SI) launched a service called AppExchange, which the company described as a Web-based applications marketplace for its users. AppExchange, unveiled at the company's Dreamforce user conference, will let users shop for add-ons and complementary applications from outside developers. One hurdle SI faces in its push to become a platform provider is its tight focus on customer relationship management and its licensing model. Companies that wish to give employees access to applications running on the company's platform will need to purchase its subscriptions for each user.
