Dummynet doesn't provide dynamic bandwidth limiting based on load
or traffic.  You can use a clever combination of bandwidth-limiting
pipes and masks to ensure that no one connection uses more that X%
of your (theoretical) bw.

You could make all non-ssh connections go through a bw-limiting
pipe (75-85%).
