netjukebox must run on a (website) web server.
But if you mean run on a isp homepage, that can be a problem.
For netjukebox to run the following is needed:
Webserver (apache preferred)
PHP 4.3 or higher
MySQL 3.x or 4.0.x
Access to a local harddisk or directory (for storing the media)
For streaming to a lower bitrate also executable right on a directory is needed (decoder and encoder).
