Every talk has a detailed page in act where the speakers are free to add more information and links to their slides, even long after the event.

For instance: http://act.yapc.eu/ye2012/talk/4069

I don't intend to duplicate too many static meta informations across different sites.

> It might be worth approaching the moderators for those channels in addition to (my preference would be instead of) the YouTube upload.

Already uploading to youtube takes much efforts, and I'm currently trying to automate this via yt-API just to be able to add "simply a title, links and summary" and tags.

The moderators of other channels on vimeo (or whatever) are of course free to upload our videos (see licence)

And everybody is welcome to provide me with automation scripts using vimeo's (or any other plattform's) API to do this.
