Well, if you are absolutely sure that your own connection always is
the path bottleneck, you could simply keep track of your observed
peak capacities, calculate an estimated capacity X and assume that X-
your current load should be available. Keeping that estimate X on the
lower end would give you a good enough approximation. This can be a
good strategy for low-bandwidth access networks that then won't have
to ramp up as slowly as TCP slowstart dictates.
But then, if you have a 6Mbps connection to the Internet, how often
is that the actual bottleneck?
