Royalty fees for open source / free browser
Apologies if this has been asked before, but I can't find a question with the exact situation we're in.
We're a group of open source developers who develop a server for multi-user virtual worlds called OpenSimulator (http://www.opensimulator.org). We are considering developing a new client-side application, and are looking into doing it in UE (among other options). Part of the decision falls on the licensing model.
Our client-side application is a browser that receives all content dynamically from servers running our OpenSimulator software. Note that we, ourselves, don't run these servers; they are like Web servers, so various people install them and run their own servers and for their own users. We also don't distribute any content as such; these operators do. We are a bit confused about the royalty fees in this case. Here are a few concrete questions:
1) I assume we (OpenSimulator devs) don't have to pay any royalties, because we distribute everything free of charge. Our license is BSD. No fees, right?
2) If the operators of our software use it for their own commercial purposes, but don't distribute the client application themselves, do they have to pay royalties? Let me break this question down:
3) Operator C is a bit more demanding and decides to take our software and make a derivative commercial product that is closed source and proprietary. They distribute that derivative work to their users. Do they need to pay royalties?

1) Correct, we only collect royalties on revenue, so if there is no revenue, no royalty.
2) I think we'll need more detail here. To be clear, UE4 is only used for the client-application, which is an executable, correct? How is the client-application (i.e., licensed technology) used/distributed by the operator in each case?
