Although I have brought a lot of high level RPC/IPC systems into production I'm really having a hard time imagining where I could use this. As far as I understand it gives me a bit more high level features (security, multicast) compared to other IPC primitives (sockets, pipes, ...). However once I'm going to use this my application (or high-level IPC framework) will be locked to Linux and no longer be portable to other platforms. So for any applications that should be at least halfway portable I would prefer something that works on the more common primitives (most likely sockets) and build something more powerful in a cross-plattform way on top ofi it (like HTTP, grpc, Thrift, ...). A full featured low-level framework makes sense if I have a whole set of applications on top of it which is not intended to be portable and uses it exclusively. Something like the Android/iOS/... platform. But the current ones already have settled on their infrastructure (e.g. on Binder), and even if new ones come up there is a high possibility that they wouldn't like at least something in Bus1 and instead come up with their own solution.
