The presence and group features will be available later this year, with screen-sharing expected for release in early 2012.
The Chatter news will be delivered under Salesforce.com's overall marketing theme for the conference, "the social enterprise," which CEO Marc Benioff honed during a series of smaller events held earlier this year and revisited during a keynote address Wednesday.
Benioff referred to the recent wave of revolutionary movements in the Middle East, also known as the Arab Spring, which gained momentum through the use of social media.
"It's not so long from now that we'll start to hear about a corporate spring," Benioff said as he strode through the crowd. "When will the first CEO fall because they stopped listening to their customers? It's more important to listen than ever before."
One component of Salesforce.com's vision involves the notion of "social customer" profiles. Traditionally, companies have gathered data points such as a customer's name and e-mail address, but social networking sites such as Facebook and Twitter provide much more fodder for rounding out the picture, in Benioff's view.
"At the end of the day, its all about your [customer] database," he said. "Are you keeping track of their handles on various social networks? Are you keeping track of their tweets?"
Benioff also discussed how customers can develop internal social networks, as well as ones for their customers and even individual products.
And he managed to produce one high-profile customer, Burberry CEO Angela Ahrendts, who seemed to have completely bought into the social enterprise vision.
The luxury clothier wants badly to connect with every customer as deeply as possible and across all platforms, as should every company, she said. "For any CEO who is skeptical: You have to create a social enterprise. Otherwise, I don't know what your business model is in five years."
"The biggest fear is we've made heavy investments on the back end of our business," she added. "That infrastructure doesn't go away." The key for Burberry will be to work with trusted partners to layer Salesforce.com's technology on top, she said.
While such talk will no doubt eat up a fair chunk of Dreamforce's running time, it fails to relay the breadth of Salesforce.com's business goals.
In recent times the company has made deeper forays into Web application development, with the acquisition of companies such as Heroku. It is also hoping to find success selling database processing as a service through its Database.com product, which will enter general availability this week.
In addition, the company is now offering a Social Enterprise license agreement that includes "enterprise-wide access to Salesforce Sales Cloud, Salesforce Service Cloud, Salesforce Chatter, Salesforce Radian6, Force.com, Heroku and Database.com," according to a statement. Pricing will depend on the company.
