> Well, here is where I disagree in general.  Because if I receive such a communications, I -will- acknowledge it.  And I think it is -fundamental- to amateur radio and just about any two-way radio service that it is incumbent on recepients of an intended radio communications to acknowledge that communication.  Usually it is taught as "roger, ..." and sometimes re-inforced by the nonsensical hollywood "roger, wilco, over and out"...

This is fundamental to radio, a system where the sender cannot know if his message was received unless the recepient responds.

I think the important distinction here is between purely broadcast 
services, where communication is always one way and from one source 
(e.g., regular broadcast radio) and a general-use communication system 
that uses asymmetric links, like APRS or a paging system.

It's like the difference between a magazine and a bulletin board covered 
in notes.  It's the magazine usage the rules are supposed to prevent, 
one person or group broadcasting material to no one in particular, and 
not the peer-to-peer bulletin board, regardless of the actual mechanics 
of the system.
