What does IM mean? Remember some of us dont know (or dont remember) all these initials being thrown at us. HSMM (whatever that means) sounds like an intereting concept, but it sounds to me like it is working a repeater, or a sattelite. You are not REALLY communicating with the middle man, but thru it. The transmitter you are hearing is NOT located at the location of the person whose call you are working - thru not valid for DXCC. You are talking from your country - to whomever has this access point - thus both of you are just working a remote transmitter from what I gather here. Again- not valid for DXCC. Not valid for WAS , etc. Now just for chatting , that is OK, but we can do that on computer links so I really dont see the advantage, except if one is not where he/she can reach an internet provider.
For groups who just want to chat, it sounds like an good procedure, or possibly for emergency nets - now that would seem an excellent way to pass information between search units, fire and police, etc, when other communications is down. Much like sticking up an emergency repeater, but allowing many to talk at one time. I am not sure that HF would be the place for it, since the ever changing propagaton would complicate connections, and would assume 6 meters (with some power available) or 220 or 2 meters would be the place. Of course that shortens the distance each network group would be able to communicate, and you would have to have more of these access point. And how do they communicate with each other?
