Description: Media is a Perl Script that creates .ram, .asx, and many other files. It uses kind of like a database to store the locations of your files.
Description: mediawrap supports RealMedia (.ra, .rm) and MPEG-III (mp3) files at the moment, but can be easily adapted for a lot of purposes (even non-multimedia files).
Description: Mimeslapper.cgi is a workaround for the confusing apache mime-type file headers, in the case of mp3 files, where a "standardized" mime type has not yet been widely accepted.
Description: a Realaudio jukebox. Present your visitors with an option box of ALL your .ra files - even those on different servers - and stream them all down sequentially WITHOUT building multiple .ram files!
