This brings up something that I've always wondered about ...

I've never really personally liked the models of transparent
distributed communications between objects for roughly the same reason
that I prefer message-passing over distributed shared memory.  From my
point of view, it seems that it is much easier to notice when you're
doing a distributed operation when it isn't entirely transparent.
But, when it is transparent, you need a whole new set of tools to help
monitor and debug what's going on in terms of frequency and number of
distributed operations because it is too easy to add a distributed
operation without realizing it, either because you simply didn't
notice something in the docs, the implementation or the docs were
lacking.

Do you find that you run into this type of problem?  If not, are there
things within your development process that help you avoid it?  Do you
have tools that help you to debug this type of situation should it
occur?

Or am I completely off the wall and wrong here and that that type of
problem never arises in real life?
