Personally, I would be reluctant to indemnify anyone over IPR in a paper
clip. This is the sad state of the patent system and it applies to every
piece of technology.

Obviously, that makes H.264 so much safer, right?

I assume this is why we've seen all these lawsuits against Google,
Microsoft, Cisco, Apple... over their use of Vorbis and Speex, right?
Seriously, I can count at least 10 free AV codecs and none of them have
had any patent lawsuits that I'm aware of.

The best interest of a H.264 patent owner is to avoid having to
disclose, wait for adoption, and then be free to ask for a lot more than
what they would get from the patent pool. This is why I consider H.264
to be a higher risk than VP8. The current Motorola lawsuit confirms this.
