I'd quite forgotten about those.

Currently, there is a build-time choice between using apple-dri, or
indirect and swrast. This is not ideal (I believe it makes remote 
clients under OSX useless), so they should all be runtime alternatives.

Those branches are really just experiments of mine to try to understand 
what that might look like before I did a similar implementation for Windows.

But I think I came to the conclusion that it was less work to use the 
existing __GLXDRIdisplay implementations as a model, rather than convert 
appple-dri to that interface and then use it as a model for my 
windows-dri implementation (see [1])

I think it's perfectly possibly to put apple-dri into a similar form, 
it's just someone has to do it :)
