Hi Vlad,
If you want to have MonoX running as a child app of DNN, you will have to place it an a sublfolder that is registered as a separate application in the IIS. After that, you will have to resolve all possible issues with HTTP handlers and modules that may have been registered in the parent web.config (either by removing them using the "remove module" syntax in MonOX web.config, or by placing the corresponding DLLs in the MonoX bin folder).
