I don't agree that the big companies would be deterred by that. The CEO's of those huge companies aren't likely to be even interested in legal matters unless it's the DOJ calling about anti monopoly practices - that's what they pay their legal counsel for. I don't think they'd give the slightest rats about fighting out the content ownership issues, especially since YouTube has already shown that it can be done. >> What's the incentive to do it all over again with little hope of success? Why "little hope of success"? No-one at that level has even tried. It's completely different from trying to take on facebook, in which you need to build the network before the whole thing works. With user created content they can start at any size.
