Sure but I don't see how being on a UN list helps fix that. Seems to me like efforts from people behind eg scene.org, archive.org (hat tip to jscott) etc are substantially more valuable to preservation efforts than convincing some folk dance geeks who work at the UN that rotating nipple balls are also cool (which of course they are)
EDIT: To be clear, I don't mean to dismiss the effort. The entire point of the demoscene is "because we can!", so obviously this also holds for getting our hobby listed by the UN.
