Hey Samuel,

The default queuing discipline on Linux is pfifo_fast.  This discipline
respects the TOS flags in the IP header.  So, provided that applications
set the TOS flags that most closely match the requirements of the
application, things will hopefully keep moving smoothly.  It might be
nice to expose this easily in our networking APIs though.  For more
information about pfifo_fast and how it handles packets with different
TOS flags, look here:
