Assuming a centralized system was doing this, it could cache the results and reduce the lookups/hr.

Because they don't take to kindly to anyone doing tons of whois looksups an hour. Trust me ;)

Why not integrate a whois date lookup directly into SURBL or URIBL? Design an encoding system whereby suspectedspammydomain.spammertld.dr.surbl.org (or uribl.com) would return the date somehow regex encoded in the IP address. Then write a nice SA rule that decodes it, also using regex. Are there any regex geniuses out there that could encode a date in an IP address?

Well this has been brought up before. It is a very good idea, however difficult to implement. Unfortunetly the date returned by a whois querey comes in a wide variety of flavors. We (SARE) thought we had all of the returned date codes figured out. Nope. New ones still keep coming.
uribl.com has some ideas on how to attack this very issue, but not sure it is worth it yet.
In short, it would be wonderful to start doing whois lookups for every domain in an email. Lots of things could be flagged off of it. Think of a sort of baysien whois DB. But the traffic would be pretty dam big.
