The IPX code only works under Windows btw. And the Linux and OS X folk don't appear to have an issue with it not being available, but still listed on the interface. I'm not really for or against ripping it out, but if it no longer serves a real use then it doesn't need to be there, so that we can simplify the networking code some. We can quite easily modify the interface code to not allow the IPX interface stuff to be used, even though it would still show up.
That's just my opinion though, and IPX support is such a minor thing that I don't really care about it one way or the other.
