I could give some more details around that. If you look at where customers deploy security, there are several places. Firstly, of course, the perimeter. The Internet-facing -- what's called Internet-facing firewall and really, the requirements there are next-generation firewall, meaning safely enabling the applications, scanning traffic for viruses, for spyware for all kinds of malware, for exploits, for data leakage, and so on. And of course, we don't F5 playing in that market at all. This -- we don't offer inspection as a viable solution in that market at all. The secondary area where security is deployed is in the data center and even there, there are 2 use cases. The first use case is the external data center, the Internet-facing data center where you run your web servers. And the requirements there, in many cases, from security perspective are pretty minimal, meaning, allow only traffic to the web servers, meaning ports 80 and 443 and then, blocking all the rest of the traffic. That, of course, can be achieved using a simple system inspection firewall and I think that's what the ADC vendors, such as F5, are doing. They call it an outbound firewall. The third area where you see security being deployed, which is still in data center, is in the corporate data center. In the corporate data center, the requirements are, again, for next-generation firewalls because customers want to control access to applications, control who can access which application, perform which functions in these applications, and also scan the data for bad things and for good things moving around. That's, again, something that we don't see the ADC vendors playing in and we're not sure whether they have the path of getting there without significant investments in anti-malware technology, in IDS technology, data leakage technology, as well as next-generation firewall technology. In terms of market size, we think that the external firewall, excuse me, external Internet-facing data center firewall is a much smaller market than the corporate data center and the Internet-facing firewall, the perimeter firewall. And these are the areas we focus at. We believe the ADC market -- the ADC vendors are focusing on the small part of the market, which is the Internet-facing security or Internet-facing firewall.
