Alright, I've got them talked into providing 2 links, one for the flash content and, at the bottom, another link directing iPad/iPhone users to the html5 site.
Now my issue is that the Edge animation has to have an audio file playing. Edge doesn't support audio, so I used the html5 audio tag and it works fine on the iPhone, but the iPad doesn't play any audio. After lots of looking around, it appears that the iPad will only play an audio file if the user clicks a button to play the audio. Is there a way to have the same button start the audio AND the animation??
Ah, bleeding edge technology...
Thanks!
