Good point - I'd missed that the response I was disagreeing with was specifically about MD5 hashes.
I'll have to think about whether the 128 bit hash of MD5 really limits the number of tables required. The 256 bit salt is added to the reduction-function-generated password at each stage of the hash chain, so even though there are only 2^128 possible hash values it still feels like the 2^256 tables would still be required.
I'm not sure, though, to be honest, so I'll have to think about it.
For algorithms that generate longer hashes, the 2^256 tables still apply, though, and in any case 2^128 700GB tables is still a bit beyond "trivial"
