Apples and oranges.  When you have the option to share memory in a
safe way you should.  When you're talking off box, then you no longer
have that option and you must use an RPC mechanism.  But don't take
that performance, fault, and complexity hit if you don't have to.  Use
threads unless you're going off box.

I've never made an argument for theads when going off box.
