depends on the box, the shaping is very efficient and is in kernel.
so it's primarily the pptp and pppoe sessions that will demand =
resources.
it's almost impossible to answer.

if i said at least 30 on a celery 1ghz, you might/might not be happy =
with
that. im sure you could run twice that on the same hardware (given it's =
good hardware
and is not the cheapest sh*t you could find).

i use a shell script called from ppp.linkup/ppp.linkdown under the =
appropriate label
(radius supplies label as "Filter-Id").

Need it be simpler?
