Is it currently possible to build this addon in its current state? I wanted to jump on board and test it out after I saw the reddit post. Unfortunately, gathering the needed dependencies and attempting to build it produces errors.

You need to add dynamic trees 0.7.4 and the latest version of Biomes O' Plenty to the libs folder of your workspace before setting up the workspace with gradle.

Dynamic Trees 0.7.4 lacks the LeaveProperties.java file, resulting in build errors. I assume this is due to changes within the last couple of hours? I ended up using the master branch, and got these errors instead: https://hastebin.com/odufotafin.coffeescript

He meant the dev version of DT that's currently at 0.7.5a. You'll need to build that first.

I got it working. It's simply incredible. I'll report back my findings to help with development.

What would be particularly useful is if you could test it in a stand alone server with a separate client. Server bugs always seem to be caught too late.
