Yes, we need to be very clear about this.

In the short example I provided, I used the dictionary key 
"streamsToAdd" to try to imply that these are the *new streams* that 
must be added to the offer. We could go the other way and require each 
offer to include all the existing streams as well. A natural way to do 
that would be to get a sequence of all currently local/sent streams with 
getLocalStreams(), add or remove streams from that structure and feed it 
to createOffer().
