According to CMSWatch, SalesForce.com is going to begin offering ECM capability. The post says the SalesForce.com CEO is boasting that customers can get rid of their Documentum implementations. For some clients who may be under-utilizing Documentum, that could be true. But I imagine SalesForce.com is going to have a lot of work to do to get its acquired Koral software at the functional level required to supplant most large Documentum installations.
