i don't think that solves any of the problems he's asking about matthew.
It solves this problem exactly so I don't know what your talking about. Plus someone would have to rewrite the block chain so no one can change it, probably too much work for a non-profit site like them.
no, because he's not asking you to "solve it" in another way. he asked some very specific questions because it sounds like what _he_ wants to do is attempt something like he describes. everything else is off-topic.
can anyone answer those questions?
