This is close enough to what the faith code is designed to do that you
could probably save yourself some work by starting with that.  I know
that back when I looked at it, it was quite simple to diddle the faith
support into accepting connections regardless of the target port
number, which is the hardest part of what you want to do here.  (In
case you want to look at what I did, anonymous ftp to and look in
/mouse/source-tree/patches/working/ - the "doc" file is a good place to
start; searching for "faith" in it will point you at the patches.  In
particular, I suggest looking for anything mentioning FAITHALL.)  What
I did goes the other way (v6 to v4), since that's what faith is
designed for, but it may be useful as a starting point for you.
