Yes you may think it is legal but (not that I don't do the same) have you read your ISP's AUP to see what you are and aren allowed to do you'd be amazed Comcast my ISP doesn't allow uploading, servers, LAN, Security scanners(locally), and a crap load more,. I was amazed on the stuff that they don't allow I think it is mainly that they are trying to hold there rights for future events... I haven't been banned yet so they must monitor there subscribers rarely.
