Van and Kathie managed to get a later version off a disk image and get 
it out of Framemaker.  Unfortunately, the paper was only half edited 
when the second attempt at publication failed due to the circumstances I 
blogged about at:
http://gettys.wordpress.com/2011/01/06/a-committee-is-a-life-form-with-six-or-more-legs-and-no-brain-lazarus-long/

Right now, they are concentrating on trying to get a consistent 
description of the proposed RED Light algorithm captured correctly, so 
we can code it up and try it.  Then they will work on finishing up the 
rest of the text for publication sometime this summer.  What I have in 
hand from Kathie at the moment is not internally consistent, though much 
longer.

In the mean while, we've started work on various AQM and buffer 
management systems, at www.bufferbloat.net.  SFB (Stochastic Fair Blue) 
went upstream into Linux to aid testing last month, and we have an 
implementation of eBDP as well with which we are experimenting.  
Wireless is much more of a challenge than the classic internet router 
case.  Please come help.

Note that the paper "Characterizing Residential Broadband Networks" by 
Dischinger, et. al. indicates that a large fraction (in their 2 year old 
sample, 30% or so) of broadband head ends are running without RED, and 
should be doing so if at all possible; alternatives are years out by the 
time they are tested and deployed, and operators running without it in 
congested systems are inflicting pain on their customers.
