Issue with Workbench is, it's like Windows. It's such a common term before it was used as the name for something that defending its use is near impossible. I recall the Lindows people were gearing up to challenge MS trademark of Windows which is probably at least partly responsible for MS deciding to come to the table and negotiate a settlement rather than go to court.
