Nice idea, but it's insanely slow on an atom processor.
Did you try http://livelabs.com/seadragon-mobile/?
I find it a little ironic that this post doesn't have the pictured Deep Zoom image embedded in the post. It should work for anyone that hits the page, using Silverlight Deep Zoom where available and falling back to Seajax where there is no Silverlight.
Does Channel 9 not let you embed such things? I noticed that the post about the synth of the Channel 9 studio didn't embed the synth either (perhaps designed to drive visitors to the site to discover other synths?).
EDIT: I now recall that Larry's own post about the moon synths of late seemed to be fine embedding the synths. Is the Seadragon viewer different, then?
