The problem is executing scripts from elsewhere. Take a look at Codea -- lets you develop Lua apps (game focus) entirely on the iPad and, when you're done, provides an open source harness for creating an App Store app. What you can't do is load a Codea project from some random place online and just run it directly in Codea. (You can post code on a website and Codea folk can copy and paste it.)
