Sure! The recent code Brian and I put up:
already has even tab-completion implemented, it uses json for the
messaging, so it's precisely that idea. Just go to
run 'kernel' in one window, and as many 'frontend.py' as you want.
They all tab-complete, send input and get output from the same kernel.
We're making sure we build the whole thing with multi-client support
from the get-go, so we don't get bitten later by issues we hadn't
We deliberately made this tiny prototype *outside* of ipython to get
the api right and see the design issues in isolation. Once it's
finished, we can build a real system out of it (once we get 0.11 out
