For those of you in the US using Comcast as your ISP, you'll know that
they now have a feature called Powerboost available in the regions they
serve.  Basically, it allows people to have higher-than-rated throughput
for the first few minutes of data transfer.  After those few minutes,
they're supposed to throttle back down to what their rated line speed
is.

I'm having difficulty coming up with a solution to do traffic shaping on
these kind of connections.  Since the line speed isn't fixed, my guess
was to set the traffic shaper to use the maximum possible speed as it's
downstream limit.  I guess I have a couple questions, more on the
conceptual level:

1) Is there a way to remove all traffic shaping from the inbound channel
of an interface...given you can't really do that anyway?  Does setting
the bandwidth value too high effectively do this?
2) By setting the bandwidth values for the WAN interface abnormally
high, will the traffic shaper still re-order the packets as they leave
the interface on the upstream channel?

I would think that if tc could simply re-order packets, with a small
queue maintained for lower priority traffic, then the throughput limits
would not have to be defined...allowing the shaper to rise and fall with
the Powerboost oddness.  This idea is wholly unfounded, however, so
please illuminate me.
