Done. That endpoint will probably be renamed at some point. I don't really like 'tree,' but I haven't thought of a better name yet.
Ye gods that was quick — thanks so much! I'm now happily using the new end-point and loving it. I made public all the updates to my screen-scraping plugin Static Discussion via Hubski. This plugin is designed to be used with Pelican, a static website generator, but the code is fairly basic Python and could easily be cribbed for other purposes. I also defined all the URLs in a conf file so that the end-points can easily be updated without revving the code. If you decide on a better name than "tree", I can just redefine the end-point in the settings.
I've been ambush-badged! Thank you, insomniasexx — you move in mysterious ways.
