Remote Desktop from PC to Apple.

We have a need to use a Windows touch screen computer to remote desktop to a collection of Mac desktops.

If I was controlling Windows from Windows, I'd use Msoft Remote desktop, which works very very well. I can open multiple remote sessions to different PCs, and easily switch between them.

What would I use to do the same thing, accessing Mac from PC?

I'd rather find something faster than VNC, which isn't great.

Thanks
