1. At present Open Access requires its own .config file. For the next major release we are considering to be able to "enhance" websites and use the standard .config files from the sites. If a standard connection is defined within the .config file, we will be able to use it.
2. We didn’t know about this project so far. What I can promise is that we will look into it, and evaluate it for possible OpenAccess implementation. That said our example that we are preparing is based on LINQ queries as a standard way of getting the data, because OpenAccess supports LINQ out of the box. So stay tuned on this one.
3.Could you elaborate a bit more on this topic? What do you mean with "including the DNN database in a module"? We will try to provide not a one-fits-all solution, but rather a learning material on how to use OA with DNN - possibly a simple e-commerce example or similar. At least those are our plans for the near future. Should we consider other approach?
Regarding the integration you are absolutely right! Always the integration into complex systems that follow certain architecture, practices and design is a challenging task. What I am able to share is that we've started Sitefinity integration with OA already. However I am unable to give you exact time-frame on this one.
