Morally wrong? I don=E2=80=99t see how morals come into this. Yes, it =
would undo some work that has been done by you, in favour of someone =

I never said phpng was evil. I said it was developed behind closed =
doors.

You, on the other hand, just said that the 64-bit patch is evil =
("applying this patch is morally wrong=E2=80=9D). Two can play at this =
game.

Relatively, yes. In absolute terms, however, what is the gap between =
vanilla and phpng + 64bit patch?
