I bought a NetGear 3800 a couple of weeks ago in order to run the 
CeroWrt test release which is used to verify codel.

So far it works well here, but I have a 50/50 fiber connection 
(delivering at least 45-48 Mbits in both directions) so I don't see much 
buffering in my end of the network.

PS. I attended a presentation by Jim Gettys, the BufferBloat Man, in 
April: The story about how van Jacobsen could not get his new AQM paper 
accepted to any refereed conference is both sad and funny:

The paper was dismissed with the comment that "it has to be wrong" and 
"the author would do well to read the definitive paper by van Jacobsen". :-)
