I'd almost used guacamole at my previous company, GKN Driveline. My boss wanted to setup soemthing to let people xvnc into servers effortlessly. We were dealing with mechanical engineers who weren't great with Linux tools. I never stayed long enough to implement it and my replacement had his hands full with other projects, but I really was excited about Guacamole and want to try it out some day. It seems like a great project, and might not get the same appreciation in tech spaces as it would in non-software companies which deal with something like Beowulf clusters or their like.
