Oh, I have no doubt that bigbank.com would like to blanket the DNS with 
discardable ADSP records.  The question is whether any receivers would 
care.  I wouldn't, since I don't consider a.b.foo.com any more similar to 
foo.com than a-b-foo.com.

Among the many conceptual problems that plague ADSP is the fantasy among 
some senders that this will somehow give them more control over what 
receivers do with their mail.
