Is that how it works? Not really used bluetooth - so it's not a code specific to your phone then but just that the sender and receiver have to key in the same code?
OK, I'll stop being a killjoy now Good luck with it. Contrary to the impression I may have given I do actually work in the mobile phone industry, which is probably why I didn't get too excited about them for recreational use at the footie. But it sounds like a novel idea - you might be starting a new craze here. Which'll just mean more work for muggins here at some point no doubt . . .
