I don't see what disk space has to do with anything. I would prefer to 
contribute to a spec that is maintained outside of the competing 
implementation's repository in the same way that I deal with other 
freedesktop.org specifications, but if that isn't the way you want to do 
things, I can live with that.

I can't really tell my users that they are using a "second class" 
implementation. You are welcome to hold that opinion.

I look forward to working together on new features and test suites. 
There's no doubt that D-Bus is helping developers put out better 
applications, and that's all that matters.

I am doing a a clean room implementation to provide validation for your 
design and specification, not because I think your code is tainted. 
Maybe you missed this point.
