Completely agree with both comments - initialise the nodes using the "product database" files, and write out specific config into a separate file (basically as you have now, but using the information in the database to initialise things).

 
I agree also about getting a "lot of data" quickly. I don't mind where from - pepper, or OZW (I did think about asking them for permission) if either of them are willing to part with it it would be a very good start.
