Excellent presentation - thank you!

Fasttrack is great but it comes at such a compromise of being unable to mark your packets / connections anymore. You guys should re-design this a bit to allow double-marking so we can properly do traffic shaping and bandwidth management with packet marks other than just `no-mark`. Since mangle rules come before the firewall filters, we could still mark our packets with a unique identifier and then also immediately mark them for fasttrack. Please strongly consider looking into this, thanks.
