Q: What is the cost per seat for the authentication service software? The customer will not want to use an external service for user authentication.

A: Using our basic library, it will be possible to build a authentication server yourself. We are working towards providing a complete open source server, so if you can wait a while the software license will be free. We do have our current Java based server up and running. I'd recommend to start test the keys using our server, and then migrate over to something internal when we get to that point.
