I agree. I wanted to say:
"Forget it unless the 'fallacies of distributed computing' do not apply to you."
but I decided not to say that.

I am using the r_osgi provider for remote services.
One of the service characteristics is passByValue. Is pass by
reference an option with this or with any provider?
passByReference is an option, but of course the provider must
support it. None of the existing providers that I know of support
passByReference.
Are there any recommended patterns for implementing
roll-your-own pass by reference if it is not supported?
With ECF, it is of course possible to roll-your-own passByReference
provider.
The most ubiquitous technology that I know of that does pass by
reference is Java RMI, which has quite a few other problems (some
related to pass-by-reference) that would prevent me from
recommending it as the technical basis of a RS provider. I'm sure
others are aware of other pass-by-reference systems and so hopefully
they will speak up.
One thing to say: from my chair the notion of pass-by-reference
itself is controversial within distributed systems design and
development. My interpretation is that some feel that because of
the inherent problems of reliability/failure detection, distributed
garbage collection, distributed consensus, and other things that
pass-by-reference requires/introduces, it doesn't make for a great
basis for reliable distributed applications.
