The method used to access the resources (videos, ...) is based on which
<res> elements are listed in the CDS response and which of those the client
knows how to access.

The least common denominator is usually http, however, if we implement
RTP/RTSP I think the support for streaming would be a richer experience
(assuming a server controlled stream) that would allow the use of commercial
cut points and other advanced features.  (I still need to research the
details to make sure I understand the features of the protocol).

HTTP is what I am planning as the first protocol, to make sure everything is
working correctly.  I listed RTP as an open issue in my previous e-mail,
since it's something I know I will not have time to address for some time to
