Thank you for the new link.

I checked the new version of the draft and I personally see no problem in
the text. There is no proprietary software requirements in the draft. It
simply defines the logic how the TURN server and web server can organize
the temporary password generation, without imposing any proprietary
requirements and specs on the software. It is mentioning a possible
communication channel between web server and TURN server without defining
any specs and as it is written that channel is not required. As it is
written, I do not think that it has to be separated into two pieces - it is
a single solid logical functionality definition.

Thanks
Oleg
