I have wanted something like this on my ipad forever. I like to make things for Second Life and I can't do that on the ipad either. I think what we could have is some piece of it though. Like, if I could import a figure into the ipad and paint it there that would be great. Maybe you can't have the whole experience on the iPad, but it would be nice to be able to do some productive work there. So far, I have not found any really useful app. Although I have managed to use Art Rage to create shirts for Second Life. There are many times when I am sitting on the train, or in a coffee shop waiting for someone that I would like to have such tools. As it is, all I do is read forums in these situations.
