umm i don;t know if you know this, but the ecomm package included is a starter package in my mind. I turned it off....mainly because you can get the same effect by using the API to control accounts, spaces, hosting packages, addons, and so much more. so my advice would to build your own solution and maninulate DNP via API.
If your a fan of .NET, this will be a peice of cake =)
PS: this is how i do mine
