There are all types of communication requirements.  Some simple, some not so 
simple.  For example:

When I need to tell a detached posting program to process an incoming order, 
There are multiple things required in the message.

My utility for such communications passes messages almost 512 bytes in length. 
Don't always need that much, but when I do, it's there.
