QoS with IPv6

Hi,

is anyone of you using the QoS-abilities (both diff- and intserv) of
IPv6? I know there should be a way doing this with ALTQ but I couldn't
find any good documentation on that. What I'm most interested in is if
anyone uses a dual-stack gateway doing QoS for both IPv4 and 6. Another
question is using an Applicationlevel gateway and keeping QoS-flags for
the relayed connections. What would be the standard way to do that?

Thanks for your time
