Not a direct answer to your question, and also probably too cumbersome.
However might be of some use to you, or other people on the list.

You could use Sun Gridengine  http://gridengine.sunsource.net
In the jargon, the second box is a submit host and the processing box is
an execution host. Nothing stops you having a single execution host.
By default, Gridengine uses a single 'load sensor' which looks a the
load average on the execution host, and has a (configurable) limit set
to 1.75.
The time step at which the scheduler examines the load is configurable
(schedule_interval)  and the load_adjustment_decay_time is also
configurable:

Its easy to configure your own load sensors (which slightly confusingly
do not have to be anything to do with load), e.g. could be free memory,
or number of free licenses
