It's a small difference, but we're dealing with really busy domain names
here, and small differences matter. When a CNAME is encountered, the
query has to be rewritten with the new name. This costs in computing
resources, adding latency. Following NS records without rewriting the
query would be better.

Ideally, I could give the akadns nameservers names inside the lycos.com
domain, and I could delegate "in bailiwick", and provide the IPs as glue.
This would be extremely efficient and fast. This is what I'll actually
push for.
