    I think the issue is with the psychology of the programmer. It's
possible to have fun playing with these communication tools, at least
for young programmer discovering them. If you're in love with C++,
you'll possibly enjoy D-bus, because it's designed with C++ in mind. And
you'll interface your pocket calculator emulator with D-bus, just for
the fun of it.  Not forgetting, of course, the company willing to make
money out of complexity.
