This isn't quite true, ONC-RPC has come with Unix machines for years
now... People usually didn't realise they had a nice reliable fast
portable RPC toolkit that came with their system, but that's because the
software industry is still very very *bad*. So few architects (for it is
architects who should choose stuff like protocols for interconnection)
actually bothered to find out what's out there. This is not the fault of
technology - it's a cultural problem in the software industry.
You don't get the people who build bridges reinventing the arch whenever
suspension bridges go out of fashion, they already know about it...

Writing code with ONC-RPC is easier than using SOAP (unless you're doing
.NET stuff where there's a lot of code that hides the complexity for you,
at which point it's about the same as ONC-RPC, I gather).
