Note that this is slightly different from what I've been talking
about: if a user trips the traffic volume limit and is put in the
lower-than-normal traffic class, that user would still be using TCP
apps so very high packet loss rates would be problematic here.
So I guess this makes three traffic classes.

If not always by choice. :-)
