IPC is totally worthwhile for native applications in any case, when separate complex components are combined into a single user session. Running the code in separate heaps reduces the chances of bugs in one application code corrupting the entire application heap.

Very hard to argue that IPC would ever be just for avoiding license. It always increases total robustness.
