Single wan multi lan issue?

[senser]

the single wan multi lan wizard creates two incoming queues (one for each lan) with both having the full amount of the available downstream speed assigned (effectively doubling the downstream). this solution assumes that, at any time, only one lan is using the downstream, right? if that is the case I was wondering if anyone came up with a better solution?

A bridged queue would be handy. AFAIK there is no such thing and therefore no way around deploying a transparent firewall and use the shaper on the bridge. Let me know if I am wrong.
