Service provider T1/PPP question

Hi Gang, This question isn't strictly operational, but I'm needing a little coaching. I am wanting to offer a broadband over T1 service and have the infrastructure in place for aggregation of many of these over channelized DS3. My desire is to simplify administration and require PPP / chap authentication, and allow ppp and ppp multilink with the minimum configuration on my side necessary, I'm thinking there could be a 'one size fits all' setup on my side. I'd love to connect with anyone providing a similar service in a cisco environment to compare notes and bounce ideas off of. Thanks. Mike-
