Servers are in the next update! Should come in April...I think this update is more focused on multiplayer. Setting up a server will cost a fee though, but I can't imagine it would be that much since the Pocket Edition isn't as spectacular as the PC or Xbox.
Now for skins, they said that it may get put in this update or not. It would be more of a side project for now. If it doesn't come out this update, which isn't promised so you shouldn't be looking forward to it yet, then it will either be in the update after this next one or the one after that.
@Link - The pros are, you get to have your own away command. The cons are I can see a lot of people misuse it. For example, "emouserbunnyqueen1 is now 'in your mom.' See?
