Agree With Michael...
Have extensive experience with Wine and Crossover Office on several flavors of Linux. Although I gave Crossover, in particular, two very good tries on two different Linux platforms - using it to run Microsoft Office as well as some less common apps - in the end, I had to go with a VM.
Faults included twitchiness and occasional crashes, also formatting glitches. I couldn't rely on the appearance of a doc I created in Windows, worked on in Crossover on Linux, and re-opened in Windows again. In the end I just felt that I had to have something better.
Everything seems to run well on the Macs I've used, so maybe WinOnX on Mac works better than Crossover did on Linux. However, I've had experience using Office for Mac to edit docs later further edited under Office on Windows, and the formatting consistency has been excellent, so I think that would be a better solution if all I needed was Office interoperability.
Glad to see someone addressing this, and I hope it works out well enough to be useful in situations - like enterprise - where reliability is key!
