Certainly, sir, but that wasn't my point.

In my experience, an organization (non-profit or not) can't simply publish their own specification and claim, "hey, this is a standard".  That would certainly be easier.

You're right, that was based on my experience with VC3.  It's possible that Theora is a bit more efficient, although any significant efficiency improvements versus the VC3 base would also increase the "surface area" at risk to infringement.

This is getting uncomfortably off-topic, but a reasonable real-world target is 300 Kbps for both audio and video, maybe less if you want it increase the chances of it working around rush hour.
