LARTC - Jul 2007 - QoS + OpenVPN

Hi, I''ve got 3 questions:

1) is it possible to do QoS and OpenVPN? I thought about doing QoS based
on IP, as there''s a couple of servers here that need to be on a higher
priority.

2) can anyone point me to a decent QoS how-to?

3) damn, I can''t remember what this one was. :o)

Cheers,
Fernando
