Funny you mention this... My vision for a DAO proposal would be asking for exit liquidity for a token a build. So basically my token would burn Hive/HBD (sent to @null) and I'd be asking for a kickback from the DAO to provide more liquidity to the users who want to cash out.

Main point being that it would be mathematically impossible for me to spend more DAO money than Hive/HBD that was already burned. That's the idea anyway.
