As mentioned in #688, I'd like to be able to connect a frontend to an existing console without manually specifying the necessary ports at the command line. Ideally, ipython qtconsole --existing would find and connect to the most recently started active kernel. If more than one kernel is running on the machine, there should also be a simple option to select one, perhaps by PID (ipython qtconsole --existing=6341).

I think that this should be possible if we store the port numbers in connection files similar to those used by IPython.parallel.

Yes, there are many benefits to using the model in IPython.parallel, including this, and I think it has always been the plan to do so. It's just that nobody has gotten around to implementing it. It should be super easy, though.

Min RK Merge PR #847 (connection files)
* JSON connection files are now used to connect files
* HMAC message signing is now on by default in all IPython apps
* Adds IPython.lib.kernel, which contains utility functions for connecting
  clients. These were mostly copied out of qtconsoleapp in order to be
  more general.
* Adds %connection_info and %qtconsole magics to zmqshell
