Hi, Helmer.  I'll paste in what I sent to you privately as I'd love to
see us restore the old functionality if possible:

We used to be able to distinguish interactive from bulk X2Go traffic
when it was using OpenSSH.  By default, SSH set the minimize-delay ToS
bit (0x10)in the IP header for interactive traffic and minimize-cost (I
think) (0x08) for bulk traffic.  That seems to have gone away in the
move to libssh instead of OpenSSH.  I do hope they restore that
differentiation so that we can shape the traffic differently.
