Your last statement is correct, the pages are generated in javascript, so you could choose how to display your data yourself :
urls looks like this :
http://empeg/ds-bin/getfid?output=js&file=test1.html&fid=xxx for displaying playlists/song info
http://empeg/ds-bin/getfid?output=raw&savefile=[filename]&fid=xxx for downloading playlists/songs
http://empeg/ds-bin/getfid?output=m3u&fid=xxx for generating m3u playlist
http://empeg/ds-bin/sendserial?serialcmds=%23xxx to let the empeg play a certain song/playlist

the getfid method with js output generates a javascript array, which is iterated in the html-templates and generates tables on the fly
