I'm not sure what you mean by userfriendly.  If you remove MLP and the
encryption, then I would consider DVD-Audio as havng the potential to be
very user-friendly.  There is no need to create a new format - just
"open" an existing one.

Yes, the official specs are "secret", but so were the DVD-Video specs,
and that didn't stop the Linux DVD-player authors.  A DVD-A shares many
of the same concepts (and very similar data structures) to a DVD-V, and
I've already started to document a fair amount of the structure of a
DVD-A here:


A very useful "feature" is that even on encrypted commercial DVD-As, the
.IFO files are not encrypted - only the .AOB and .VOB files are.

And the recent news about the reverse-engineering of ALAC (and other
codecs in the past) casts doubt on the fact that MLP will remain
proprietory forever.
