limiting bandwidth at certain times during the day

[Ronnel P. Maglasang]

Current implementation of ALTQ and also PF is not dynamic. You apply changes
(e.g. new Queue parameters), you basically have to flush all the queues 
and reload.
That means, "pfctl -Fall" followed by "pfctl -f new-pf.conf"

You can achieve this by creating a script that will called from cron. Be 
aware of
the effect when flushing all the rules though. That would drop existing VPN
sessions.

I am not sure if there is an on-going project to support dynamic ALTQ/PF.
