Add a try to import fabfile_backend.py from the ReceptorMarkerDev repo - that file contains some private functions that you will use to update the server from this repo; add some additional settings to the Vagrant environment with that import in mind, since some imported functions might expect them; also update the reload function so that it can reboot the server, too, not just Vagrant.
Add some notes in fabfile.py about whiche functions are duplicated elsewhere in the project. They're duplicated in your private repo that is used to bootstrap the server. Keep an eye out for that.
Fix bug that caused different fabfile.pys not to import because you were trying to import a module that was removed and that was causing the rest of the imports to not get executed.
