two modems

[BUDDY HOLLY]

Hi, I have got two pc's, the old one is running on windows 98 and the new one is running on windows XP I have just signed up for the Orange livebox, I am already on broadband, At the moment I am using the live box on wired setting. First question, Is it possible to run two modems from one phone line using an adaptor(ie The new livebox and the old Speedtouch)? When I finally get the livebox running on wireless do I have to have the box next to my pc or can I put it down staires where I have the phone which I will use for the free phone calls?, Can I set my windows 98 pc to work using the signal from the livebox? If not, can I plug the Speedtouch modem into the phoneline upstairs?
Any other suggestions?
