 I can run many xmms in the same time. This is not a proof??
Also I can see in the 'ldd xmms' that is using the lib from nas:
        gusti@r40:~$ ldd /usr/bin/xmms
            /usr/lib/audiooss/libaudiooss.so => 
/usr/lib/audiooss/libaudiooss.so (0x40014000)
            libpthread.so.0 => /lib/libpthread.so.0 (0x40024000)
            libSM.so.6 => /usr/X11R6/lib/libSM.so.6 (0x40039000)
            libxmms.so.1 => /usr/lib/libxmms.so.1 (0x40052000)
before Nas (or without the variables : AUDIOSERVER and LD_PRELOAD) the 
'ldd' give:
        gusti@r40:~$ AUDIOSERVER=
        gusti@r40:~$ LD_PRELOAD=
        gusti@r40:~$ ldd /usr/bin/xmms
            libpthread.so.0 => /lib/libpthread.so.0 (0x4001f000)
            libSM.so.6 => /usr/X11R6/lib/libSM.so.6 (0x40033000)
            libICE.so.6 => /usr/X11R6/lib/libICE.so.6 (0x4003c000)
            libxmms.so.1 => /usr/lib/libxmms.so.1 (0x40052000)
 So I'm right. Yes ??
