[BA[ Unless SDES is indicated as supported in the SDP blob provided by createAnswer(), "manipulating" the SDP offer to add it probably isn't a good idea. 

That's one reason why we need understand the precise semantics of createAnswer().  To (mis)quote Christer:  does createAnswer() indicate a (subset) of what the browser can do, what it would prefer to do, or all that it is capable of doing?
