I think the people who solved business process problems using
RPC systems would disagree with what you said. OS developers
solved OS problems. Application developers (by and large, ones
inside mid-to-large size enterprises -- the only ones who'd really
bought into distributed applications) solved different problems,
including business ones. Those solutions weren't as visible.

As I said, retro: people have been doing those with RPC systems
for decades. That is, when they haven't been building them straight
on top of databases ... anyone with middleware-style requirements
was very likely to use an RPC framework to build their "services".
The sea-change the "web" brought was a cross-platform GUI,
based on HTML. How the back-ends talk to each other has
often been either an RPC-ish thing or a messaging framework;
the "web services" buzz doesn't seem to change that in any
