Hi Willem,

One detail, by looking at the MSRP relay logs I notice that both  
parties reserve a session in the relay.

Could this be avoided, so that only one party reserve a session in the  
relay? Or is it inherently to the fact that the desktop sharing can be  
in either direction so you must reserve a session prior to agree upon  
the direction?

Adrian
