If you can think of a way to make an alternative DNS root take off, I'm all ears. If you can some up with a non-hierarchical alternative to DNS that (a) is as fast as DNS, (b) isn't prone to spoofing or squatting, (c) isn't riddled with security and trust issues, and (d) actually works, I'm also all ears.
Personally, I don't think it'll happen any time soon. The only successful DNS fork is North Korea's.
