Nope, ahh well, I agree that the use of UTXOs in the Satoshi client today by no 
means a directed towards a DHT, though it does help speeding up validation (db 
lookup to check if an output is indeed unspent).

However, an alternative way to bootstrap and validate transactions exist, 
needing only the UTXOs and not the rest of the blockchain history: An 
authenticated data structure storing the UTXOs in a DHT.
