What are our Options?

Options
We have a game we are developing with PUN. It's currently running through the cloud solution and one of the client acts as the Server. We want to create a Dedicated Server that players can run instead of having a client be the server. What are our Options? I see that Photon Server has a free 100 server redistribution license with 50 CCU per server... I'd really like the server to be a Headless Unity Instance though so it can do Physics and continue to use PUN... So I guess that just leaves continuing to use the Cloud and have each server create it's own room?
