I agree with you up to a point. However the code in Webkit is under a 
permissive license so will be available for porting to other browser 
engines at a later date.

The contribution of code by a particular individual to a particular 
engine is not the concern of the W3C working group in my opinion, and 
further more should not be discouraged. As Phil said, he'll work on this 
"offline" and I'm sure we can follow updates on his progress here or in 
the Webkit repo.

I think the discussions here would benefit greatly from having more 
people look at and contribute to working code wherever it comes from and 
I'm really happy to see more of that going on.

I think the proof will be in the pudding here, as they say. We have some 
a use case in this thread (FM/"analogue" synthesis) and some noted 
problems (glitches, pops etc.). It'll be interesting to see how each of 
the implementations cope with this use case as they mature, as that will 
inform the standardisation effort.
