Isn't this also basically the point of LEDBAT and CONEX? For
applications to sense congestion and back off aggressively -- i.e., to
time-shift themselves into the future?

+1. No, +100.
At the end of the day we have a limited amount of bandwidth

can help matters if people co-operate where it is in their interests.
Whether or not we choose to do so does not in any way justify using
the fact
that I have limited choices in bandwidth provider to ensure that my
options
for content and/or VOIP telephone service are similarly limited.
One area that might be fruitful for cooperation is in bulk time
shifting of
traffic. I am not so much talking about packet level prioritization
here. I
am thinking more of when I choose to back up my systems over the net.
RFC 3662 is aimed at this sort of application. Whether it has been
usefully deployed, I cannot say.

The way I look at it, the net is a bit like the power grid in that
there is
an opportunity to reduce capacity requirements by shifting tasks
from peak
to off-peak. In particular I have several RAID arrays that I would
like to
back up with a total of something like 2Tb of data.
At present there is no incentive for me to play nice other than the
risk
that my activities will clog my local net. In fact it is arguably
in my
interest to do at least some of my backups at peak time when I am
not using
the net since that encourages my ISP to upgrade their circuits. I
don't
actually do that but others might.
It would be nice if there was some way that really high bandwidth
apps that
can tolerate long latency could negotiate a good time to do this
sort of
thing so as to minimize inconvenience.
