Data processing/viewing, i.e:

The python code is getting executed by an engine server, which has a
long running engine process.  These engine processes can be any
executable, but what I imagine is that we would provide a python
environment with CKAN libs. So I might fire up my browser, munge two
datasets and then publish the result back to CKAN - doing it on
codenode would allow: transparency (you can see what I have done),
repeatability (you can rerun my code and test it), data-local
computation (run the code near the data).  You could use some kind of
queue, but the engine process allows interaction with the data - since
you can interact with the engine while running.
