You may find topics and items of interest also in the treatments that Niven and Pournelle gave "Inferno" and its recent sequel.
I loved both “Inferno” and “Escape from Hell.” Niven and Pournelle did a great job on them. I take it you’ve also read N&P’s “Lucifer’s Hammer”? If not...you should. They are unusual in the sci-fi genre for having a very different political worldview, IMO.
Oh! You should pick up Varley’s “Steel Beach” if you get a chance. I think any Heinlein fan would really enjoy that one.
