If everyone just promises to not violate copyright then it would be on the individual to keep that promise and not the group.
I brought up the copyright issue because I would hate to see this forum closed down by some misguided (in my opinion) collaboration between private industry and governmental agencies just because they can. If the plan is to collaborate to develop a ROM for housing personal samples, or samples that one has a right to make archival copies--or even to make compilations selected from ROMS one owns*, or compilations from sample CDS, softsynths, etc. etc., I don't think there's an issue.
(*or even if you have the free Proteus VX and those samples/presets and want to put them into a ROM for E-Mu hardware, etc. etc.)
With all due respect--which you know I have--I don't think the copyright issue is out of place here.
