The 64x32 pixels of the default resolution skin look rather poor if one uses an HD texture pack, but that's the only resolution allowed to for upload to the profile on minecraft.net. I can of course play in offline mode, which gives me the texture pack's default
char.png, which I could replace with my favourite HD skin, but in SMP everyone would look the same (if the server doesn't require online at first, that is).
Is there any possibility (vanilla, client mod, Bukkit plug-in, etc.) to walk around with HD skins in an HD world?
