Open the songs list and automix mode to other protocols

i am using your wondeful application on my ipad but the songs list is just displaying itunes transferred songs as the automix mode do.
Could it be possible to open in song selections another external drive like an Sd card and a wi-drive using a wifi connection protocol like Webdav or an URL with an ip address o rbrowse an Sd card like /var/mnt/mount1/ and automix with these solutions?
Best regards
