Holdposition,
If you are going to go Broadband, set one up one account for home and one account up for work. (Once you go Broadband you will be spoiled almost immediately and will not want to use dialup again.) In each location you should setup a router so you have the safety of a hardware firewall and every computer at that location will be able to share the single broadband account.
You can use any company for your broadband service and then just get one AOL for Broadband account if you feel you really need to keep AOL.
Take Care,
Richard
