In the software business, there are no downstream capacity constraints. It's about printing as many copies as you can and selling them. In this business, it's more like a factory. You have to manage capacity and the quality of the capacity. There are a lot of implications in that factory metaphor.
Security services are like manufacturing.
There's a learning curve, so you make more money on your millionth widget than you did on your first. Planning for scale is another important aspect, just like you need a factory that can increase production. We've tried to organically develop this, so the services are different from the companies who are just sort of adding services to their current businesses. We can offer multiple firewalls, but in terms of intrusion detection, the only product we'll support today is our own. That will change over time, but I don't think we've seen a lot of concern from customers that we're forcing products on them.
