Well this is not really an easy request. First if you are using TCP there
is no way to limit speed on client or server side effectively. It would be
easy to react to the configuration parameters that are sent using the
newer code (post 1.7), but if you really do not trust folks to not edit
their source to abuse that as well then you could get in trouble. If the
clients are windows machines then you have no recourse because windows
does not properly listen to ICMP messages saying a UDP connection is
closed or not available. If any of these approaches sounds beneficial let
me know.
