Have you looked at the WebKit team's proposal for 2.5D graphics and  


These are now on track to become W3C standards and are already  
implemented on iPhone (2D portions only on desktop WebKit currently).

Also, have you looked at how touch and accelerometer events work on  
Safari on iPhone?

I am excited to see contributions from Nokia, but we would want to  
make sure that advanced WebKit features remain consistent in API  
between platforms.
