Maybe, just maybe ein now works under both IPython 2.x and IPython 3.0 (or what is the development version as of this commit). And by works I mean open, closing, saving notebooks and communicating with the IPython kernel. It is good. Also fixed a bug in kernelinfo - os.uname is not implemented in Windows (or mac, probably), but I think socket.gethostname() is available on all three platforms.
