Is duplication really that bad?  So long as the communities are vibrant, 
why should we care?  Also, have you factored in different requirements 
and different implementation strategies for the projects in your list of 
duplications?  I've always liked the idea of software Darwinism.  Many 
different exciting ideas with the community deciding which ones are the 
good ones.

IMHO, having unified projects stifles that diversity.
