My original input to Chris Tchou and his friends at Watson.org (original home of the MOD Archive) was legal advice regarding content ownership. I suggested that MOD/IT/S3M content, because much of it came without a license or was freely distributed with encouragement from the Amiga MOD community, was essentially public domain content because it had be released, without a distribution license, yet was still copyrighted to its original owners.
This sort of legal exploration became the basis for my delvings into other archival artistic endeavors (YouTube). See: Mod Archive

The Mod Archive - a collection of mods. This started as a joint project with several friends during my freshman and sophomore years at CMU. It was created because all of the existing MOD collections on the net had no screening process whatsoever, or were woefully small, making music browsing a painful experience.
