Agreed this is of course the best way to secure lots of servers.

And if you like the look of "wrr" as a qdisc,

(and it does seem to have some very advanced features -
  such as the ability to "spot" large downloads and
  automatically decrease the available bandwidth for that
  connection for the duration of the download -
  although I could be wrong in my understanding of this) ,

then you can still use this qdisc with a NATing router,
so have a look at their site anyway.

The suggestion of a bridge was intended as a simple "no fuss"
solution which can easily be bypassed in times of need -
such as component failure - by simply taking the cable out
of the bridge and plopping it straight back in the router.

I was of course assuming that your "friends" would take
care of their own security, thus removing the burden of you
even telling them about the traffic shaping as well as
preventing you from having to manage all their port forwarding
requirements.

I'm sure the whole business of traffic shaping is far too
complicated for any one answer to be correct even one percent
of the time so I accept that this answer may be useless for you.

Good luck!

Leigh
