Code-named Eiger, the software will allow businesses to run Windows applications on a bare-bones PC with the bulk of the business logic performed at the server.
According to Steve Bink at blog site Bink.nu, the client will need to only meet the barest of requirements by today's standards: a monitor supporting 800x600 graphics, a Pentium-class processor, 64MB of RAM, a 500MB hard drive and a network interface card.
The Bink.nu entry also mentioned the existence of a second thin-client application, with the code name Monch, that features everything found in Eiger with added support for mobile devices, wireless networking and VPN support.
On the flip side, putting the bulk of control into one server introduces a single point of failure. If the server goes down, everyone connected to it goes down, though that can be alleviated to a large extent with backup servers and other redundancies.
According to a Microsoft spokesperson, Eiger is in the very early stages of development and testing at this time and that it is too early to discuss the features to be found in the software or a possible release date or pricing expectation. The company confirmed customers are testing out the product and providing feedback.
Officials believe Eiger, which they refer to not as a thin client or a smart client but as a ''mid-client'', is designed to reduce the total cost of ownership of the company's desktop infrastructure -- companies that might not have the resources to update to the latest hardware and operating systems.
While Eiger will have more capabilities than a traditional thin client, the Microsoft spokesperson said in an e-mail statement it will nonetheless be less functional than a full-blown Windows XP-based PC. The software will also still require maintenance.
''Eiger will be designed to get the most out of legacy hardware without going beyond the capabilities of that hardware,'' the spokesperson said in the e-mail. ''For those customers that are unable to upgrade, we are working to make sure that they still have a good solution to incrementally improve their infrastructure -- and this solution is Eiger. When a customer is finally able to upgrade their hardware, Eiger will provide a great migration path to Windows XP or to Longhorn running on a new PC.''
Microsoft's solution departs from the traditional thin-client model in that Eiger will allow companies to use older computer systems to act as the end user's machine rather than just a terminal client using just a monitor, keyboard and mouse.
