I assume you guys looked on Nominet...?? That's a handy site isn't it!
Also Be/O2 connections are fairly easy to snoop on if they're using the ISP supplied routers
they're stupid enough to leave Telnet on. Rather annoyingly, the Thomson Supplied Firmware doesn't allow you to change it. You can change it however if you "Flash" it, but that voids the warranty :-( Hence why I don't use their supplied kit.
Virgin Media do the same. But they get very very unhappy if you use your own kit such as a Cisco Cable Modem. Though that's not because they know the SuperHubs are rather poor. But because if you're clever enough to make it work with your own kit, then they know you're clever enough to change the startup commands to get more speeds than your actually paying for!
