Like similar elements in Microsoft's Passport and .net My Services initiatives, Sun's instant messaging will allow users to chat in real time across a network using text messages. It will also allow searches to identify employees with specific skills.
Details of the product will not be released before the 23 October launch but it will probably mark the fruition of Sun's Connexus research project.
Neil Ward-Dutton, research director for e-infrastructure at analyst firm Ovum, said, "The battle with Microsoft is a red herring. It sounds like the product is based on Connexus and possibly the linked Awarenex research which places it more in competition with Lotus Sametime."
Connexus combines a personalised contact list with an instant messaging chat window. When a contact is selected, the user can choose to see more details about them, such as key skills.
The addition of Awarenex research would extend this service to mobile users or staff working for partner companies and suppliers. Together the products would allow workgroup members, inside and outside the company, to collaborate on projects.
