Crap...  Why do I need to make decisions?

OK - lets think on the go here...  The two options we "want" to support
based on submitted patches are:
1) Disabling the low speed timeout
2) Setting maximum download speed

In the future, we might also add a parallel download option.

I'm guessing these want both global config values and command line
options.  Anyone want to suggest what these could be.  I'll choose the
colour of the bikeshed.
