Resolving the problems with the Sender header has been addressed in
the DRUMS working group.  There was rough concensus at the San Jose
meeting that the "Sender" header refers to a deliverable mailbox.  So
constructing it from NNTP authentication info may be impossible.

I'm working on an independant header proposal to address the trace
information issue.  It should be coming out as an internet draft in the
next couple days, probably with my suggested filename:
"draft-newman-msgheader-originfo-00.txt".
