As note, for Darclight's post I just used the d20 Dice Bag on the SRD (http://www.d20srd.org/extras/d20dicebag/).  It doesn't have a history-saving function, but you can't mess with the dice rolls on the website, you can essentially ONLY copy & paste them from that page.  If I need to come up with some alternative, GM, please let me know!
