@minrk, we'd discussed this in the past, so I'll just make an issue here so we can track progress and ideas. I'm finding myself so often connecting to existing kernels in many ways, that I think it really would be useful if we could replace our current

--existing --shell=12663 --iopub=14174 --stdin=16920 --hb=58880

with just something like:

--existing 12345

and have that be sufficient for the rest of the connections to 'just work'.

When we add connection info as files, that will be the only info you need - zero ports, one file. This is already necessary to deal with existing security issues.

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
