Terminal server (Score 1)

I don't see why you would want to use Linux for windows. We are starting to use a solution where the main user OS is Linux but for legacy apps and MS-only crap we have a windows terminal server (2003) setup and use tsclient to access it from linux. Everything runs in the environment it was designed for and you don't have to buy licenses for anyone except those that NEED access to windows-only apps. And the price is actually less by my calculations than crossover plus the MS-app once you get to a certain number of licenses. (We are non-profit which also helps a lot;)

Your mileage may vary... Some restrictions may apply
