How about a public s3 bucket curated by a non-profit?
Tools exist already to upload to S3 from practically every device, especially Android.
Curation would be much harder, but there is a lot of money in philanthropy and I could see some deep pockets contributing to that.
YouTube is fine as a means of promoting and gaining awareness - world should know about these things, but it's not rational to expect a corporation (aka people within it) to act in any other interest other then it's own.
Seems like this could be an interesting infrastructure non-profit for YC to fund.
At the least, we probably need “upload video to archive.org” mobile apps to make this as useful to journalists in the field as YouTube currently is.
If the Archive grows as a journalistic distribution channel, it might then face YouTube's issues of copyrights, piracy, and other criminal use. However, the Archive could apply goals that are more compatible with journalism than YouTube can. Maybe sufficient philanthropic support could make this possible.
