1 problem with your textures. when running the textures while in a multi player server it makes all other players invisable. I just ran accost that this morning.
I have looked into the issue and unfortunately there is nothing I can do about this as Red will need to add in support for texture packs for servers..... which I think he will do down the track.

Maybe we will add support for new textures (which does not replace existing ones, but append to the list) in the near future, at least for singleplayer. Of course it would be a goal in the long run to add the same support for multiplayer, but this would have a relatively low priority at the moment (first we have to get a pipeline for serverside texture packs ready)
