Firefox OS includes pseudo-native implementation, with some work still getting farmed out to persona.org. Ozten and Jedp are working on the beginnings of truly native support in desktop Firefox. We've held off on pushing too far in that direction while we toyed with the API and data formats, but things seem to be shaping up.

If you guys get it stabilized and working I wouldn't mind helping get Konq to support it (time permitting, of course).

Not sure, but the good news is that the current method in itself works great.
