I'll be honest that I'm not familiar at all with the security devices mentioned. I read all of the comments. I wonder what is so different in SL? One comment was about being scanned without consent. We are scanned every place we go (in the usa) without our consent. We are watched at street lights and scanned for security purposes. I don't think it's right, but it's being done. So what is the difference? Is it because SL is thought to be able to be a 'utopian' world so peeps don't want anything to bust their bubble inworld? I don't get it. Facebook is linked with so many businesses that if you are buying something at some internet store next time you go into facebook your store, and even the item you purchased, will be popping up in your ads on your home page and wall. Talk about evasion. How many people in here use ANY applications in facebook, for example, (not to pick on facebook alone)? Every application you accept you are giving them 100% access to your most private information, pictures, comments, etc. to be used at their discretion without any required future permissions from you. There is no such thing as not being 'plugged' in unless you live as a hermit somewhere, and even then, there's someone watching you...
