I agree in spirit, but the idea of everyone starting at the same end of the download does indeed go against some of the core ideas of bit torrent.

Personally I think maybe something should be built on top of bit torrent to accomplish this task. To me it's a case of being careful when re-engineering underlying protocols because of a higher level need.

Anyway, it's a nice hack, but I kind of understand where the client developers who refuse to do this are coming from :-)
