this mornig I found what may be the simplest answer: Using FTP.
You connect to Music FTP server as superuser $000, which puts you in your home directory. in this case /$000: and allows you to transfer all it's files.
How you do the trick ?
Simply typing in your ftp client the directory you want to transfer: for instance? cd /$adm: and voilá you are now in this directory and can transfer files from it.
Probably meedling with ftp server configuration you can go to the root dir musicx:/: and see all the directories, but it's not my purpouse to be "super super user", but to? easily backup user's source files to the pc, linux, etc.
