I dont really want my mid-level domains to potentially be hashes - I want domains at all levels to be intelligible and, optimally, to be named what they are, i.e. foodinchicago.com or food_in_chicago.com or food in chicago.nlp_name Perhaps enabling spaces in domain names is possible? Since spaces in filenames are allowed I don't see why spaces in names shouldn't be allowed. And then you could have a default root domain for natural language names - .nlp, for instance, and then just assume that name when someone types in a natural language URI with no tld. We could use something like NameCoin for this TLD to avoid collisions.
