While I was travelling (snowboarding in Japan) I followed this thread and I'm actually quite heartened by the responses and I had quite a few in my inbox as well. Lots of ideas to chase still. The gist of my thinking is that starting a funded startup and put some good development power behind it would be the most fruitful avenue. Zipline and Zipline-live can become a very important part of the financial ecosystem but in my opinion, Quantopian has taken an US-centric institutional route, I would like to take a tiered approach by developing and contributing to zipline and zipline-live and make it such that it's easy to keep an algo's code for yourself but let other people trade with it and they will pay a contribution. The crux in my view is data, multi-asset capabilities (trade on multiple of exchanges (IB, Robinhood, cryptos, etc) at the same time: enable multiple currencies, enable European and Asian exchanges, etc, etc ). Then the hard part: a server farm that is stable where one can move an algo to without disclosing the code and being able to rent out your work. Take zipline, Quandl , C2, Quantconnect and a proper reputation and verified trade system, hustle and mix and try to do this in a proper way.
So lots of work that will need funding.
I have spoken to several people who would like to be involved and would like to provide funds and I'm exploring several avenues, from self-funding (by me and a founding team), VC funding, ICO offering that would power the ecosystem and some other ideas that got shot down (robbing banks and old ladies)
Let me take a week and nail some stuff down and I'll come back. Zipline is too beautiful for it just to be a hedgefund tool. Hedgefund power to the people is a more wholesome framework... and hedge and other funds can join the party as they want.
