[IPython-User] Parallel question: Sending data directly between engines

I'm going to rehijack this thread back to the simple peer-peer case.

I was playing with the interengine example with numpy arrays and running
into issues. It looks like its sending the array's data but none of the
object data.

In [1]: import numpy as np

In [2]: run interengine.py

In [3]: A, B = rc[0], rc[1]

In [4]: A['data'] = np.ones((2,2))

In [5]: send(rc, 0, 1, 'data')

In [6]: A['data']
array([[ 1.,  1.],
       [ 1.,  1.]])

In [7]: B['data']

Is there a clean and fast way to make B's data variable a numpy array? I
suspect this is handled already in the high-level interface. I wasn't able
to locate this bit of code. Is there somewhere in particular I should be
looking for this kind of thing?
