You can implement it ("or something like it") on any system. In fact there is a plenty of those. Remoting isn't impossible either (e.g. DCOM, CORBA, GRPC).
No it is not (well it might be with antiquated CORBA/DCOM stack but these are just examples, something newer like GRPC would be easier, the point is that it's solvable).
Also the original complaint was about explosion of language combinations and I just pointed the solutions to this are well known.
