As folks like Keith and Bryan have already noted, there are plenty of OpenSolaris happenings at OSCON this year. I'll be at the OpenSolaris BOF at 8:30pm Wednesday evening, so stop by if you're around.
I'll also be knocking about the conference/Portland in general Tuesday night through Friday. Leave a message for me at my hotel (503-222-0001) if you'd like to meet up for a beer and talk about OpenSolaris, Solaris, or smf(5). I'll even be happy to help you write an smf(5) manifest for any open source or commercial service; conditional only on your willingness to publish the manifest for others to use. :)
