What is really wrong with *X*...
It is cross platform, concurrently available, proven, virtually "effectively" bug-free - by that I mean "noticable to the end user", typically runs on the "just behind bleeding edge" hardware, well documented APIs, freely available to anyone that wishes to use it, scalable to support many different ways of depoying it, a bit overweight in the Network Protocol, modular... etc... etc...
The ONLY thing I see coming out of that fork he wants to make, is direct rendering. Well I believe that will make it extremely platform dependant then. You will have tremendous "activity" in the *NIX environment for INTEL Chipset... Maybe the PPC, but all other platforms that currently support X very well... will effectively stop progressing.
If you want Direct rendering "ala peanut butter sandwiches" get [link|http://www.microsoft.com/windowsxp|this product], it has the corner on that market.
