I’m glad to see that Vimeo updated their player so it’s finally possible to run HTML5 in embedded players. So now it works on iPads and iPhones (only for Vimeo Plus customers on the iPhone however). I first recognized the update after finding the Vimeo videos on my sites to be dead. A couple of hours later i found some references to the Vimeo blog in the forums. I had to spend last evening updating the the sites but now the videos run again.
