Very nice looking program - can certainly see myself using it to keep track of what's going on on my Mac.
One thing I've noticed though, is that it doesn't seem to be catching network activity that's taking place from the command line. I'm running an SSH session, and just tried pinging a server from the terminal and it didn't see either of those. If you can add that as well, then it would be even more useful.
It should notice command line ssh connections (it only logs new connections, not already established ones).
Pings aren't really connections, so it doesn't list them. I understand that it's not perhaps the best choice for it to act this way. Putting this into consideration.
It's probably using some high-level Cocoa network framework, and not kernel-level functionality like netstat does. So my guess is only apps using the same high-level net framework are listed.
Because of the user interface. It's a dumb issue, but Lion changed the way table views work. Getting from 0 to MVP was about twice as fast with the new Lion features.
It's something I consider improving, though. Fundamentally, the same app should work on 10.6 too.
