title: sharing a namespace across multiple ipython notebooks
body: <p>I would like to work with several ipython notebooks at once sharing the same namespace. Is there currently (ipython-1.1.0) a way to do this?</p>
  
  <p>I tried creating different notebooks on the same ipython kernel, but the notebooks don't share a namespace. Also, I've been able to use a terminal console alongside a notebook on the same namespace using the answers in <a href="https://stackoverflow.com/questions/19479645/using-ipython-console-along-side-ipython-notebook">Using IPython console along side IPython notebook</a>, but I couldn't find the notebook equivalent of the --existing argument.</p>
  
  <p>Thanks a lot</p>
