Absolutely... Given that it'll understand CIDR '/' notation, it's a real
blessing. It also handles multiple addressing, and multiple addressing
schemes, considerably better. And handles tunnels sanely. And makes the
tea.

I've no doubt that it's friend, tc, is just as nice to use, but
unfortunately:
a) my brain leaks through my ears when I try to understand it.
b) from what I understand, it's not as useful if you only control one
end of you narrowest link (ie, the modem, or DSL line).

Otherwise I'd try using it to prioritise half-life packets over boring
HTTP ones.

Dave.
