users of xacct?

I'm interested to hear from those of you that might be using xacct, and your thoughts on the product. To keep traffic down on the list, just reply to me. If you are providing cable modem service and using xacct I'd really like to talk to you. For those of you that ask for a summary of the replies I receive, I will pass opinions, not names. Thanks, -Mark -- To a dog, you're one of the family. To a cat, you're one of the help.
