Okay just finishing collecting feedback for the next iteration on this and other forums. It seems like the features people would like to see the most include:
- Tokenizng assets other than the SPY, especially ones that are hard to get normally.
- Having a more decentralized oracle system.  This is the last piece of centralization in V1.0, so the next iteration will definitely need to drop this.

Other requests that are on the list:
- Allow USDC/DAI as collateral in the vaults instead of ETH.  This will allow margin reduction. 
- More formal code review.

Let me know if there are other top request I'm missing.  Or if you want to upvote any of the requests above.
