In the bug comments, Barry said he gets the same 401 error on "list-machines/", using Trusty as well.
I'm using Saucy now (when I started trying to fix this I was in Raring). I haven't tested in Trusty.
My first bet for that 401 error was "Is the server accepting requests from computers running Trusty yet?", BUT the response includes 'OAuth realm="Ubuntu Software Center"', so I don't know. I thought I had renamed all occurrences of the credential.
Answering you last question: I haven't changed any system files for that (I think). And last time I tested this, I booted a Live DVD in Virtualbox, copied the source code from the host PC, and tested directly. Obviously, I had to start Ubuntu Software Center and login to my account there (and then to test if the sync was working).
