This page contains some information about a wrapper of the libofa library which is used by third party applications that want to retrieve a PUID from musicdns.org: http://search.cpan.org/~pepe/Audio-Ofa-Util-0.04/lib/Audio/Ofa/Util.pm It seems to indicate that the fingerprint might change if you apply lossy compression on a file but you can be sure that the PUID you get from musicdns.org is the same as before. I think the PUID is just the unique key into the musicdns.org service if you like to retrieve additional metadata later. The plan was probably to use musicdns.org for other things than just a PUID generator. I'm pretty sure you don't need the PUID for MusicIP. If you have used picard or similar tool to get Musicbrainz id tags into your files, you should need the PUID for this later on as you already have the musicbrainz id tags which is unique.
