One obvious, if nontrivial to implement, idea: simple, low-cost, distributed authoring tools to enable collaboration of geographically distributed production teams in creating YouTube-like content, including "one-click publishing" to YouTube and similar sites and strong integration with consumer-level capture devices such as mobile phones (e.g., flexible iPhone and Android recording apps). Perhaps a less-ambitious place to start, at least bandwidth-wise, would be music — some sort of "GarageBand in the cloud" to enable easy yet powerful "spacetime distributed multitrack recording", again with strong device support and easy publishing of the results, possibly even including track sales, or at least an "e-tip jar", and possibly even an "instant compulsory license" tool for cover songs. In both cases, I'd focus on tools to create "entry-level" original content rather than "mash ups" or "remixes", though the latter would, of course, not be actively discouraged (modulo "unfair use," of course).
