There is no "command to execute"! IPython provides a module to import from
other python apps (pate plugin, which is *embedded python app*). So, as
Philipp already replied, python_console_ipython plugin *just* import it! No
magic! No commands to execute or anything else... just "usual" import. And
what will be imported depends on what ipython provides in any particular
distro. For example, in gentoo, it is possible to have ipython "compiled"
for Py2 and Py3 at the same time. And command `ipython` will use a module
corresponding to the current default `python` version. But, Python version
the kate is linked w/ couldn't be changed at runtime! So, if we are linked
w/ Py3, python_console_ipython will import `ipython` module from python3
site packages dir. Same for py2...

kate do not (and can not) be *linked* against ipython! again, as Philipp
already said *it is not a native library*! it can't be used from C++, only
from Python. And it's up to distro makers to provide ipython module
compiled for the same Python version as kate... As I notice above there is
no problem to do so in gentoo. Dunno what about other distros: are they
provide bilingual python stuff for both versions or for "default" only...

That is absolutely CRAZY idea! and better even wouldn't consider it...
PS. Personally I don't understand why you still discuss this... Definitely
if user wants to run smth Py2 specific from ipython, he will do it from
console (using `ipython` CLI). Why he ever want to run it from *ipython
embedded into kate* ??? As correctly being noticed by someone above,
ipython inside of kate is targeted to kate plugins developers... it is not
the same as `konsole` embeded into kate! it is not a general use tool!
