I second the suggestions made so far, about not hard-coding the player into the <dao>.  

Speaking of "ark," though, could somebody explain in plain English why or how an ark is better/worse/different than a persistent URL or URI?  I've looked at a few of the sites that discuss it including https://wiki.ucop.edu/display/Curation/ARK , but I can't seem to wrap my head around what the difference is.  So far as I can see it's just a URL that happens to contain the string "ark" -- surely there must be more to it than that??
