A time ago I found a pretty useful tool to connect from my win workstation to linux machine: the tool is named NOMACHINE and allows to connect to KDE desktop with no functionality loss and full color support (sometimes that’s very important). It saves me a lot of time when I work in Photoshop and need the same time to manipulate with html/sliced images on my local development server. The only thing which confuses me is functional keys handling, for example in full scren mode Alt+Tab sometimes switches me to windows desktop instead of switching KDE desktop windows. Hope developers of the tool will add a special keys sequence to switch between Nomachine client and win desktop (like rdesktop has: Ctrl+Alt+Enter).
