Fair warning to Wine users right now, I believe there is a bug right now either in the latest test build of wine or winetricks (maybe both) that is causing dotnet20's installation to fail. This may be just an Arch Linux only problem, but I thought I'd throw that out there to people who might consider an update.
Update: Seems like something was missing and a reboot fixed it. (I just switched HDs for my OS. It was broken on both the old and new build, I assumed Wine was the issue.)
