This is a little like jQuery Mobile's ajax loading strategy? Though I like that it's just links, as doing ajax form submits in jqm seems like it always needs data-ajax=false with ajax forms needing to be very well thought out.
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.
