not so fast!  :)  just so everything is clear:

FLAC's replaygain support is just a tag.  it is not altering the
stream in any way like mp3gain does for mp3.  with FLAC it is up to
the player to interpret the tag and alter the level.

so the new reference tag just tells you what reference level the
analysis was done against.  if you change the tag, it will only
confuse the correct play level because the other gain tags are
based on analysis at the original level.

it is possible to create an analyzer that does use a different
level and use that to rescan a FLAC file, and update the tags.
but I don't know of any such thing yet.  also, I don't know of
any player that interprets the reference level.  ideally the
player would also have a "player reference level" (say 89dB)
and if it saw such an re-analyzed FLAC stream by some as-yet-
undeveloped tool at 83dB, it would change the replaygain value
by 6dB for playback.  but no player I know does this either.

what I think is more likely to happen is that everything will
just use 89dB as a reference and players should effect users'
preferences with a preamp option, which most (all?) players
already have.

whew!
