There may be some overlap in the future - I have yet to really dig into hive besides the couple times I poked at the code. It'll definitely be something I look at when I revisit the concept of chainBB.
I'm also glad you took the time to response and that this resonates with you as well. I have a lot of respect for what you're building and working on within the Steem ecosystem and think that work is crucial towards our growth. Thanks :)
