Desktop remoting is emerging as one of the killer features of Google's Chrome OS, as it allows even small low power devices to connect to a regular and powerful desktop PC and run traditional x86 or Mac OS X apps.
Microsoft is following suit with a "Web-Browser Based Desktop And Application Remoting Solution", which shows a similar approach and could have some interesting implications for multiscreening environments.
The patent application submitted in June 2011 states that the technology would use a proxy server to establish "a HTTP session with the client and a remote presentation session with the client. The server generates graphics encoded with a remote presentation protocol and sends them to the proxy, which re-encodes them as video and sends them to the client for display in the web browser. The client captures user input at the web browser and sends it to the proxy, which encodes it with the remote presentation protocol and sends it to the server to be processed."
Desktop remoting can serve a variety of purposes, but it's most critical application today is the transfer of application to platforms that do not support them. We already know that Microsoft has a very capable web browser as far as graphics display is concerned, which would give the company a good reason to use desktop remoting between x86 Windows, Windows RT and Windows Phone. As long as a x86 Windows machine is available via an Internet connection, a full screen browser could almost eliminate all software concerns that are currently plaguing Windows RT.
For platform synergy, desktop remoting could end up being an important bridge technology for Microsoft.
