Governance model ? - Open Source Community Owned Not For Profit exchange

Premised on the observation that the current state of infrastructure is and has been a major impediment to the adoption of crypto-currencies, and the conjecture that public infrastructure should be owned and operated by the community as a not-for-profit resource, I'd like to solicit suggestions for governance models and supported features for a public not-for-profit bitcoin and altcoin exchange based on an open source model.

For example:

How would operational and management decisions be made, by whom and how would they be selected ?
What type of license should the source code be provided under ?
What type of licensing or revenue capture model would be appropriate to ensure adequate operational funding.

What mechanisms should be used to decide which coins to add for trading ?
What features should the exchange provide, currency PAIR trading, options, futures, derivatives, ETFs ?
What authentication model should the exchange support/require ?

Creation of malicious negative trust to suppress free speech shames the bitcoin community.
