I just installed 0.8 onto a 1.2.2-release box. The interface looks great, but so far its either not capturing discussions or not logging them. I can't tell which. I haven't played with this software before so anything I can do to help you test this?
It transparently redirects the connections, it's not a BPF listener. You'll need to reconnect for it to see stuff - there's actually some annoyances there that I want to look into (changing settings drops all in flight IM sessions). Interface isn't mine, the package was originally created by ryan wagoner, I'm just updating it and working on adding the new functionality.
