so MAC addresses don't get propagated past layer 2; or so I thought. noticed a particular variable this morning after signing onto Starbucks wifi: http://digital.starbucks.com/?MacAddr=, and there was my iPod's hardware address, urlencoded but plain as day. so even if you don't log into anything, you're being tracked by that unless you randomize it before you move to each new AP, all day, every day. wonder what good that does Starbucks, or if it's solely at the behest of the NSA. of course they could have easily hidden it in an encrypted hexadecimal string, or base64 encoded, and few would ever notice.
