Yes, but if you enable outbound protection in the built in firewall, it is very complicated to manually set up rules allowing it for apps since it will then block everything, including things like Windows Update. From what I read about the firewall notifier is that it greatly simplifies the process by first enabling the outbound protection and then alerting you when attempts are made and letting you decide what to do from there. It then creates rules in the Windows firewall based on your decisions. The Win7 Firewall Control is actually another firewall built on top of the existing one and using the same API's but it does a pretty good job, even in the free version, which is what I'm currently using.
Like I said, the notifier app looks interesting and I may try it out when it matures a little more.
