But you still need to know NOT to use them. That's all you need to know.
Thats a good quote...
I think somewhere on here the other day we were just discussing how the WAN device is the bottleneck. Of course there is also the shameful limiting of upload speeds with ISP's. If you have 5mb to 10mb up and a decent router you should be fine.
Even when we run into places where they are dropboxing the crap out of their bandwidth I prefer to limit the non-realtime protocol that is causing the issue over creating a queue for RTP streams. In reality a queue can only have priority when there are other things queued.
