I don't think it could be a problem : we can automatically encrypt the
with receiver's public key (any algorithm, we must choose, but I'm not very
good in crypto), and then insert encrypted message as another file. No
contact is needed, and nobody can guess either the inserted file is a message
or a mp3...

As you say, expeditor identity can be stored in the encrypted message, so
the receiver can know who sent it. Using digital signatures, we can be sure
of the expeditor's identity, but allowing someone to be anonymous could also
be a good idea...

Anyone interested so ? I must precise that Freenet does this, so we can see
how they do, and either their way is good or not.
