Check it out and tell me what you think, its almost ready for release. Its using paypal but im adding other billing options, authorize.net and 2checkout. Its completely db driven, when you install you enter your remote user and pass, server etc, no editing required. Even autosignup package creation. You can set quota, userlimit, domainlimit, sql limits all in the control panel. Guys most of my scripts are free but this one is going to be for a meger price, let me know what you think. For billing, it starts a paypal subscription. But with authorize.net it will have a cron job. its in paypal sandbox mode right now, heres the dev account login, email@example.com pass genocide and use any paypal account to complete the purchase. It doesnt really charge right now.
