I've gotten the gazebo simulator working on OSX, so that's a possibility too.
You can get access to the code by signing up for an account on the
WPILib site. They may or may not give you access. Additionally, binaries of all the eclipse plugins/etc are available without restricted access if you know the URL for them.
I've got access, and I'm not on a beta team, and didn't sign an NDA. I've been providing access via a private github repository to individuals who are helping out with the RobotPy project.
