About 12..9 months ago I started working on an Acrhive bot for Slack -- the eagle eyed of you may have noticed that there is an "Archie the Archive Bot" in most of our channels. It's not currently running but https://github.com/ashb/slackarchive is pretty close to being in a workable state: it imported the message export for history, got new messages, had a UI with searching -- about the only thing missing was it didn't show threads (visually, it shows all the messages from them).
It seems like there is demand for this so I can fire it up and deploy it somewhere more persistent than my laptop :) -ash
