Well, sure, it would work, but it is a security concern. You are proposing that you create a service that punches inside your customer's firewall. That typically is only done when there is a strong reason for it, not just for your analytics.

In the same spirit, you pushing updates to servers running on someone else's infrastructure is a problem - they need to be in control of their own servers, so odds are they want to do the updates themselves.

In short, this setup may be good for you, and may work for some customers, but you are fighting against some standard IT practices.
