As I mentioned before, don't worry about something that ambitious yet.  We'll 
first concentrate on getting the basic system up and running, before we can 
load some monster genome analysis into it, which probably depends on a zillion 
other libraries.

The paper was indeed interesting, and it shows there is actual interest in the 
scientific community for this kind of environment.  Providing facilities to 
ease up the packaging of support data for public distribution, for example, 
would be a good future enhancement, so that a notebook can be bundled easily 
with all its supporting data files for others to execute, check, experiment. 
But first things first: let's cross that bridge when we get to it.

I think this one was settled already by Robert's clarifications.  But don't 
worry about random number generators at this point, that's not our initial goal.
