Of course our interest is making a great distcc for clang.  My main  
meta-point was that by supporting other compilers for subtasks of the  
compilation work you can stage more of the implementation without  
relying on everything in Clang to be working perfectly.  And despite  
Argiris great work on C++ parsing, full support for C++ compilation is  
a long way off, so supporting other compilers for this task might be a  
huge win for adoption of a new distcc.

Also, it's better to get measurements early on where the performance  
issues are because that effects fundamental aspects of the design.  A  
rapid evolution of the distcc design with testing and real numbers  
will not only make the new distcc both faster and more scalable (per  
your goals) but also potentially more stable and usable at an earlier
