Removing T/TCP and replacing it with something simpler

[Karim Fodil-Lemelin]

    In the case where all connections go through the SATLINK and are 
splitted by proxies, it make sense to use this knowledge and not 
renegotiate cookies for every connections since we know there is only 
one path to the internet and that all SATLINK connections will support 
(T/TCP or whatever name it will have). Do you have any plan to include 
that knowledge in your design or is it too much of a special case to 
really care?
