Hi all, and thank you for the feedback so far. It is indeed canvas/ HTML 5, and I don't anticipate problems with IE. Google's iecanvas.js brings canvas to ie6&7, and ie8 has an implementation of canvas, though I haven't tested it thoroughly.
The most exciting parts for me are iPhone/android, and in general the idea of a full styling/scripting language for maps, that is, GSS. You can read a bit more about GSS at cartagen.org.
