FYI re XEP-0176 (Jingle ICE Transport).

(I have not yet investigated the patents in question. Those who wish to 
remain untainted may not wish to do so.)

What is the appropriate venue to discuss these disclosures? Seeing none,
I reply on the MMUSIC list.

The patent holder states that it shall grant licenses "on reasonable
terms and conditions", but the terms and conditions are not defined.
Therefore this is merely a promissory note. A definition of the terms
and conditions would be helpful.

The following text is an improvement over the original version:

     In addition, the Patent Holder grants a "free" license to any
     prospective licensee if such prospective licensee commits to
     license its own essential patent(s) or essential patent claim(s)
     (if any) for implementation of any IETF specification for "free".

The newly-added words "if any" are particularly helpful, since some
entities (e.g., open-source projects) do not typically hold patents or
make patent claims. Will such an entity need to explicitly register with
or apply to the patent holder in order to obtain a license? What
penalties will ensue if such an entity does not obtain a license?

The text does not define the procedure by which a prospective licensee
can become a licensee. Is that procedure still to be defined? Presumably
the procedure will include a mechanism by which the prospective licensee
"commits to license its own essential patent(s) or essential patent
claim(s) (if any) for implementation of any IETF specification for
'free'". However, in the absence of a defined procedure it is difficult
to know.

Given the strong and widespread interest in the NAT traversal
technologies specified in draft-ietf-mmusic-ice, more clarity regarding
the licensing terms, conditions, and procedures would be appreciated.
