For the hosted service, you'll want to determine what are some of the core functionality that your users will care about. For folks who don't want to do deal with setup and maintenance, they could be a completely separate crowd than the folks who will be downloading your open-source version. You'll have to balance the needs of both audiences. What's critical will be to start chatting with people to get an idea of what they want. Inexpensive options like DigitalOcean are great (we're on there as well) for testing out ideas. However, you'll have to balance technology choice, ease of implementation and costs as well. Feel free to shoot me a message if you wanted to chat further.
