It's perfectly legitimate to have two domains names pointed to the same IP. Altavista itself even does this (altavista.com, av.com). Although if you actively submit both they could perceive you as a spammer. From what I've seen Av seems to just delete any duplicate listings it finds leaving the orginal (things like blabla.com and www.blabla.com), but if your aggresively marketing both I wouldn't be suprised if you get blacklisted.
