Hi!

I've been following the discussion about jingle here a bit.
And I just read
http://www.xmpp.org/extensions/xep-0177.html

A question arised when i read section 4.1 (End-to-End Data Encryption):

   In order to secure the data stream, implementations SHOULD use
   encryption methods appropriate to the transport method; in the case
   of UDP, that would include Datagram Transport Layer Security (DTLS)
   as specified in RFC 4347

Who is the server and who is the client in those connections?
Is the server side the initiating entity? And does that mean
that all clients which are able to init such a transfer have
to know about DTLS?
How is DTLS negotiated?

Or am I missing an unlinked XEP?

cu,
   Robin
