Ah, great - in that case I'll just wait to see how that shapes up
before trying to hack on anything myself.

This makes sense, although the more typical use case for me is wanting
to start up ipythonqt normally, executing something that will take a
while, and realizing this only *after* it's running. So an additional
key-binding along the lines of the "detatch" function in screen is
what I was thinking of. e.g. something that will close the qt
frontend without closing the kernel. Of course, I can do this using
the --kernel-only flag now and then connect to that kernel, but this
requires planning ahead, something I do my best to avoid :)
At any rate, as you say, this will hopefully become much more natural
to implement when the parallel framework is in place - I just wanted
to point out this particular use-case that I would find very useful.

This is indeed the sort of thing I had in mind, but it seems natural
to me to expose it as an option for an ipython profile file or
something similar in the .ipython directory given that's currently
where all the configuration goes. Presumably the Traits Qt backend can
be examined to figure out how to do this?
