I think I got the right blocks and signed correctly; my local QT client returns true upon verification requests.

All of that verifies for me.

Primecoin's has both.

I find it a bit disappointing that for all of the extreme amounts of computational power that goes into Bitcoin's blockchain, all we get is a verification of the latest block. There's no interesting analysis possible of the proof-of-work statements. Primecoin at least doubles as an enormously huge chain of mildly interesting computations.

quick, lets make UFO coin. every signal decrypted and processed is a block. first person who decrypts it a processes is rewarded the block. now we have another scientific coin. see where i'm going with this? you know, at first i was being facetious but you just might have sold me. maybe scientific computations offered by prime and any future coins like it could offer a pseudo-backing for the currency, much in the way that physical gold and silver once backed physical paper money

Doing analysis of external datasets would be a bit difficult to accomplish in a decentralized cryptocurrency, and the work has to be extremely quick to verify that it's correct, so many types of computations are out of reach sadly.
