Just FYI: Phylotastic is working to use OpenTree's global tree and its repository of study trees and put them in various places (embed on EOL, let kids in a zoo build a tree on their phones of all the critters they see, etc.). We'll continue to reach out to you when we need something (filing an issue, etc.). but thought you might like to see what we're planning and discussing in case it affects any decisions on your end. Feel free to lurk or chime in.
Our github organization:
https://github.com/phylotastic (note that I'm moving the older, NESCent-hackathon projects we're not supporting moving forward to phylotastic-legacy)
Best,
Brian
