Quoting jim stockford (jim@well.com):
My guess is that Christian is well aware of licensing and permissions legalities.
With one possible exception. Concerning Google, Inc.'s footage of the SVLUG event, Christian said:
The Digital Tipping Point uses by-SA. I would not recommend a by-NC-SA license or any other configuration using the NC restriction, because it means that no one can ever put up any footage on any site that *might* generate revenue in any way, shape or form, not even Google ads, which are rather ubiquitous.
1. This is not what CC BY-NC-SA 3.0 (current version) says, at all. Its restriction against commercial use is narrowly scoped to the actual file access, and is covered in section 4(c):
You may not exercise any of the rights granted to You in Section 3 above in any manner that is primarily intended for or directed toward commercial advantage or private monetary compensation. The exchange of the Work for other copyrighted works by means of digital file-sharing or otherwise shall not be considered to be intended for or directed toward commercial advantage or private monetary compensation, provided there is no payment of any monetary compensation in connection with the exchange of copyrighted works.
So, Christian either didn't bother to read the licence he was commenting on, or didn't read it correctly.
2. Even rights specifically denied by an attached licence can be granted as required for individual recipients. E.g., I make some of my works available under GPLv2, but am willing to grant other rights to people who can explain to me why they need them.
3. Also, as a special case (to remind people), the _licensor_ is never bound by the licence terms. So, Google, Inc. as copyright owner of the SVLUG Flash video can do pretty much whatever it chooses with that work, including putting ads next to it.
I'd take his assurance that he'll record the event properly, maybe get some notion from him as to how he'll approach the speaker wrt use rights.
In particular, I'm sure he'll use something less open-source hostile than Macromedia Flash. ;->
