OMG, I'm an exceptionally fast reader and I don't have anywhere near enough time to read all the "terms of service" contracts for all the software & services that I use. I hate it but I'm forced to "skim" many of them because there's just no friggin' way in hell that I could possibly read all that. The only way I could see this possibly working is if there was a standard rules agreement and people had to list where there rules deviated from that. Otherwise, it's just not happening baby - it's a pipe dream.
It's likely entire communities would adopt similar contracts, sort of like Blue Sky laws. Thus you'd only need to know what's common in that area and anywhere that points differ could be automatically pointed out for you.
