How do you know they haven't each capped their upload rate at 1 KBPS?
  
 Because they're selling packages with advertised download rates of 7Mbps and such, if they capped upload off at 1Kbps, users would never see those speeds.  Asymmetry has an impact on TCP which is what I was alluding to.  Asymmetric upload and download is a fact of life with cable. (And DSL, actually).  The affect of asymmetry on TCP is discussed in lots of places (see eg. http://homepage.ntlworld.com/robin.d.h.walker/cmtips/downup.html ).   It also doesn't hurt to have a DOCSIS 2.0 capable modem. 

There are a number of reasons why Will might be having this issue in addition to the ones I've mentioned.  Several of them are technical and, yeah, Cox shaping bittorrent is certainly one possibility. But it's one out of several and without more technical details there's no way to no for sure.

This is not about technical limitations, it's about sabotage.  Cox has given 
me a symmetry of shit.  My download is 40, my upload is 55KB/s.  There's no M 
in those numbers and I might as well have DSL.  All the RST packets, I'm 
sure, are flooding my leg of the network but it will take me another 17 hours 
to get the rest of the file.  Oh well.

To some degree this isn't even a cost issue but a technical one.  You are
tied to certain physical limitations inherent in the medium.  Until there
are some changes in how DOCSIS works and some spectrum is made available on
the upstream side, you'll never say faster upstream on a cable modem
