IPC in Sequence Diagrams?

Here's a question about modeling design class interactions using
sequence diagrams.

What approach do you use to show that objects from different processes
are talking to each other? My sense is that you wouldn't want that
level of detail in every sequence diagram. More likely, you'd want to
just show the objects passing messages via their methods normally, and
perhaps indicate with a note when a process/component boundary is
being crossed. The framework for handling the actual
process/component message passing would then be defined in one generic
sequence diagram in an infrastructure package.

This is just a sense of what to do, not based on actual modeling work
completed. I'm looking for comments from folks who have actually had
to do such modeling. I'd like to know how you did it.

Thanks much!
