Re: [codec] Opus codec licensing

[Jonathan Rosenberg <[e-mail]>]

The Skype IPR declaration uses standard in the lower-case sense - any 
standards track RFC. It does not mean that it only applies to a full 
standard protocol.

For those not familiar - IETF standards track documents can be in one of 
three categories - proposed standard, draft standard, and standard. A 
specification, in theory progresses through these three phases in that 
order, each with a different RFC assigned. In practice, the vast 
majority of standards-track RFCs are proposed standard, and never make 
it beyond that stage.

Thanks,
Jonathan R.
