This bears some resemblance to copyrighted software that is free for the home user, yet costs money for the corporate one, even though the user can just-as-well download the home-user SW and run it for corporation uses. Too expensive to actually check, so in most cases you just don't bother, only quoting your official line to your existing or potential customers and generally trusting the honesty of your customers to pay you when appropriate (And Israel is definitely a wonderful, albeit unprofitable, place to go about with that idea). The difference is that ISP's are by far less profitable businesses than software developers. For them, such "NAT piracy" could easily prove a financial death blow. espicially if every such pirate is one juicy business less to milk for money on one side, and one more round-the-clock broadband hog throughout the day. For all those with software-piracy ethics this may be a point to consider. :-) ---= Miki Shapiro =------------------ ---= Cell: (+972)-56-322433 =-------- ---= ICQ: 3EE853 =------------------- ---= Windows Programmer in Rehab =--- ------------------------------------- "If at first you don't succeed... ..
