Hey guys,

really glad to hear that you'll both be taking on the co-editing of this 
spec! 8)

If there's anything I can do to help please let me know. We'd definitely 
be happy to contribute feedback on the javascript examples and we also 
have a range of animations and 3D phone models already setup that could 
easily be used to visually annotate the spec.

In terms of enhancements I think there's two key areas that would be 
good to look into.

First, it would be great if the API also supported data in a format 
other than just Euler angles. e.g. As a Quaternion and/or a Rotation 
Matrix. NOTE: On the topic of Quaternions, I also found this interesting 
post linked from inside some of the three.js documentation 
- but I'm sure you guys know a lot more about this topic than I do.

Second, the "original orientation" point that Rich raised a few weeks 
ago would be great to clarify. If different devices provide a different 
reference frame then we will end up back in the same "confused UX" 
situation we have been in recently 8(

Also, it seems that the latest Firefox Beta on Android now implements 
the spec more accurately so we've removed the special code fork we had 
for that now. So this means we just need to remove the jumpiness from 
the Opera implementation and then the three leading browsers on Android 
are all in a workable state - w00t!
