In any case...what I think would be a cool DLC is a mini mission where ya gotta hack the old CIA or FBI data base at some point...but in doing so you wind up with a PipBoy mod that updates regularily (in real life), and uses the info from an online wiki.
I currently play with my comp on next to my console so that I can access a FO wiki - just to be sure I'm getting all the backstory on a certain NPC or basic walkthrough on a quest/mission....to have this info available on my PipBoy - at any given moment would be fan-flippin'-tastic!
...k...I'm done...thanks for all the great games Bethesda!
