[IPython-dev] Connection info for qtconsole kernels

I just noticed that on the current master, the message indicating the
connection details needed to use "--existing" are no longer printed
when an ipython qtconsole is started, but instead prints the kernel
pid.  Is this intentional?  Is there some way to output that
information when the first qtconsole is started, or retrieve it if I
know the kernel pid?  It seems to defeat the point of the --existing
option if it's impossible to get the information needed to make the
connection.

I know "--debug" includes the information, but printing all the debug
information to be able to connect a second console seems
confusing/difficult. (Oh, and the debug line says "--external
shell=##### iopub=##### stdin=##### hb=#####", which I think is
supposed to be "--existing shell=##### iopub=##### stdin=#####
hb=#####" - I can submit a bug report on that if desired, although it
seems pretty trivial)


On a related note, with the newapp configuration system is there any
way to connect to an already-existing kernel via a terminal-based
frontend, or is qtconsole currently the only way to do this?
