In all honesty, it is a good product but it is also not that difficult to create it, I mean not difficult in the sense that to me, this product can be produced by an experienced developer within 1 month for most (if not all) of the functions. My personal opinion is that when the product needs 2+ person work years to develop, it has a selling value. Otherwise, big companies (usually with strong IT staff in house) will not buy into your product.
I would suggest the following product features in future:
1. Integrated with social media, esp. twitter / facebook.
2. Integrated with Exchange (and other SMTP servers) where people can send an email as an on-demand request to get what is needed.
3. Provide PowerShell administration interface
