From this article at Inforworld, I see M$ has not changed their monopoly tactics yet:

Quoting from it:

That means using any software other than Microsoft's to view an XP desktop from Windows 2000 or any other operating system would violate the company's license agreement, in case you care.
For someone who used VNC quite a bit to control PC's around the world in my previous job, that sucks. After using PCAnywhere, switching to VNC was the best decision we ever took, as it was fast, flexible and robust (and free). No way would I want to have to use a M$ product to control a PC halfway across the world over a satellite link.

M$ is still trying to strong-arm other companies out of the Windows market.
