can I insert the same phrase you used "and unknown submarine 
patents"?  Otherwise you mis-characterize the position.  What is 
more, no-one with deep pockets has yet used the Ogg codecs seriously, 
and therefore there is no "honey pot" to attract the submarines (hm, 
do submarines like honey?).  This is not the case with H.264 and AAC, 
as we have made, um,  some money using them, among others.  More, the 
major players who are likely to have patents are under a RAND 
commitment for ISO standards;  they are under no obligation at all 
for Ogg.

Are you, Sylvia, prepared to offer any kind of indemnification for 
this open-ended patent risk?  We have had this discussion before, and 
I am not sure that new arguments are being raised;  the Ogg codecs 
currently offer us more risk than reward.

ISO standards are indeed open standards.

I (and others at Apple) are aware that the situation is not ideal, I 
assure you.  I wish I could see a better solution than the current 
"should".  Indeed, as you pointed out, an ability to add codecs would 
ameliorate the situation.  Lastly, I feel a little hurt that Apple is 
being so attacked when we take great efforts to develop, implement, 
promote, and interoperate open systems and specifications, while 
there are others in the industry who make no such efforts.  Could the 
rhetoric against us be toned down a little, please?
