Use git-config to setup a remote tracking branches. Could use git-remote but it complains when a remote of the same name already exists, git-config will just silenty overwrite the setting every time. This could cause wierd-ness in the remote cache if the url changes between calls, but as long as the repositories are all based from each other it should still work fine.
