Well, reducing the ceil of A by 1/8 of B's bandwidth in the tree I
posted earlier would do that.

The bandwidth in HTB is dynamic, as classes are allowed to borrow
bandwidth from other classes depending on their rate-ceil settings.
In the tree I posted, the bandwidth behaviour is as follows:
10mbit will be reserved for C at all times, B can use up to 20mbit,
A has 70mbit reserved, but can also use 20mbit of B if B is idle.
If the borrowing/lending bandwidth between HTB classes is not
dynamic enough for you, the only other option you have is to
somehow externally delete/create new HTB classes on the fly,
which is not a good solution in most situations.
