Nice idea, but keep in mind that you are hashing into 2^32 space, so collisions will occur, unfortunately and we'll end up with directory again :-/ Even if they did not occur you would need to keep up the registry of names anyway (is it Peercoin or PPCoin, Testnet or TestNet ...)? -- Best Regards / S pozdravom, Pavol Rusnak
