It instantly reminded me of JQM's ajax loading too. I've had good experience with it, but the framework (JQM) feels quite heavy and definitely an overkill for something like this. If turbolinks provides just this functionality and with much lighter-weight (and hopefully similar browser-support as JQM) this could be quite a promising approach.
