have you checked out alertpay, i have been using it with a system i purchased, it works great for me, untill vshare comes up with something that works better, and im sure they are working on this, take a look at www.alertpay.com, and take a look at the system released by a fellow vshare webmaster. http://www.blazingeagletube.com/mods/index.html

do a search on alertpay here and you will see the posts, hope this helps.
