I don't have a clue, but it sorta doesn't matter, because:
(a) There are tons of mismatched cards in the field, and they're a
    continuing problem no matter what Hauppauge does in the future;
(b) Multivendor setups will of course not be guaranteed to match
    anyway (though it'd sure be -nice- if everyone agreed on 0dB);
(c) There are input-to-input (RF vs composite etc) and channel-to-
    channel variations that can be at least as large, and -they- need
    a solution, too.

My wishlist item at the wiki points all of these out, though it does
comment that the card-to-card issue is the biggest problem, in my
opinion.  (The rest might be more easily finessed, or you might know
that channel X is always 9dB louder than channel Y, but you really
-can't- know without poking around---and should not be -expected- to
know---which particular -card- recorded a program if you have several
cards that all have the same lineup.)
