If it was me, I'd set her up with a different broadband provider on the new phone line. BT, Wanadoo, Tiscali, NTL, Zen Internet, Pipex..... they all have differing IPs.
Hey urb, haven't spoken since Christmas, hope you had a good one. That's a good suggestion. I'm with tiscali so I'll probably hook her up with bt (because I'm sure they have a nice 2mb package). Thanks.
