What's going to be tougher, though not a hard call right now, is the decision on LP rewards for new pools. Do we split the 1M/year of SPORTS for swap.hive LP between Hive/BTC pools, add additional inflation pools for BTC or take from other areas like content rewards. Right now our inflation looks like, in approximate terms:

8M - Content (4M author / 4M curation)
1M - LP Rewards (swap.hive)

I was originally planning to do 1M for the DAO but after finding the DAO could take on the role of @sportsprojects I think it will have plenty of funds available to it for us to issue on an as needed/desired basis. Any approved projects will still essentially be new coins on the market since they've been locked up before but it won't be coming from newly issued coins.

I've not been in the portal for tribes yet but I imagine a lot of these contracts will be configurable on the fly for future changes. I'm sure there's going to be continuous new features for tribes to take advantage of and tribes will want to be able to adjust as needed. I'd like for us to stay right at that 1B/year area myself but as always will defer any changes to the proposal system.
