@Anatoly: As Matt mentions, IPython architecture is based in a two
process model. All code is ran in an external process called Kernel to
which connect any number of clients which can have different interfaces.
Right now there are only three: a web based one, a qt based one and a
terminal one.
At Spyder we need to create the kernel through the external console so
that the Variable Explorer and the Object Inspector keep working on this
model (specifically because the Variable Explorer sends and requests
objects in pickle format, something the kernel doesn't support
natively). As Pierre mentioned before, this is a temporary step until we
figure out how to communicate with the kernel directly. However this is
a long term project because it doesn't seem an easy task right now
@Matt:It hasn't been an easy task to implement a more complete
integration with ipython 0.12+ but our aim is to have the best one we
can develop. Just a couple of minutes ago I pushed several configuration
options for the clients and with them we have now a bit more powerful
application than ipython's own qtconsole(!), because every client can be
configured separately from each other.
Please try it out and tell me what you think.
Cheers,
Carlos

This may be conjecture on my part. If Spyder can leverage the power
of Ipython .012+, it will get a huge boost in usefulness for free. I
don't know how much explanation is necessary if you guys follow the
Ipython project much, but the kernel model and the ZMQ communication
protocol opens up almost endless possibilities. Using Spyder
interactively with Notebooks, development of front end/back end
systems by attaching to already running kernels, debugging, are just a
few of the things that seem simplified in my mind. I probably don't
understand it well enough to even come up with a good list. I'm not
saying that defining roles are a bad plan by any means, but don't lean
toward dropping support until you fully understand what .012+
<http://ipython.org/ipython-doc/rel-0.12/whatsnew/version0.12.html>
can do.

Hi. Thanks for the heads up. I wondered why so many IPython references
are still in `external console` plugin if it is not going to handle
IPython. Now it is clear that `external console` will still handle
IPython to a some degree. Although it is not clear what for?
Perhaps an outline (a blog post perhaps?) about roles between IPython
kernels and clients in relation to Spyder IDE will make it more
interesting for developers out there.
P.S. I am actually not a fan of mixins - they are hard to reverse
tracing. You know - "debugging is twice as hard as writing the code in
the first place.', so unless there is clear distinction of roles in
derived classes, I'd think twice before using them. Mixin is like
"from blablabla import *" - it's useful sometimes, but not it not a
good idea in general case. =)
