            unblock it.  Rather than give in to their demands, there is a serverside
            option which extracts direct links to the h264 encoded MP4 video files.
            These files can be loaded in a custom player to allow Vimeo playback without
            triggering their dumb API domain block.

            It's a little bit hacky, but my only other option is to keep buying new
            domains every time one gets blocked.  No thanks to Vimeo, who were of no help
            and unwilling to compromise on the issue.
