And, a follow-up thought that, perhaps, a compliance test might be a nice thing to add to RFCs (at least those that proceed to standards) - with IETF or ISOC or maybe ICANN maintaining a reference server to test against. Well, it's "rough consensus and running code" and not "rigorous compatibility and RFC compliance". last I checked, standards required two separate interoperable implementations - so which one would be favoured and chosen for your reference server?
