Well, sounds like you have a plan, go ahead and implement it :)

Some pointers:

- get the global ipython object via get_ipython()
- its .user_ns is your user namespace.
- in there, the 'In' variable contains your inputs.

I'd just add this as a normal function initially loaded in your
startup file.  Once it's working the way you want it, you just need a
few lines to expose it as a magic for convenience.
