With the help of a whole cast of characters, we've got our "reference implementation" Pachyderm project server up and running. It's just a clone of SFMOMA's Making Sense of Modern Art production server, so we may need to clean out some data and media, but it's working (apparently) well.
I've tried creating a new presentation (a Zoom Screen of an Ansel Adams photo), and the creation process went quite smoothly. I'm having some trouble actually viewing the result, but that's probably a minor thing.
Cool. The Pachyderm is roaming the Hinterlands once again!
