The reason to remove IPX was not "it's old" but "nobody cares about it". Since
you do, the other reason remaining is "there are no users". If you want to
maintain it anyway, great! To begin with, you probably want to verify that the
code isn't broken in HEAD.
Good, although, if you don't intend to use it, I think we could use you
elsewhere :)
Er, the number of people who want to maintain obscure protocols (for
compatibility needs I assume) is only going to decrease with time. If
nobody cares now...
