Same thing. A piece if information is sent from someone's domain to 
someone else's domain. Whether that involves network traffic is not very 
important; the most significant bit is that someone's code provides 
information to someone else's code, and the two "someone"s don't know 
each other.

That applies no matter how you package the piece of information.

I know one instance where they tried to get away from packaging the 
information as a piece: A Windows thing called TWAIN where the two 
pieces of code (which may or may not be linked into the same process) 
cooperate across the API to build a UI. TWAIN does get away from the 
packaging, but the result is not nirvana.
