Yes.  It's common to have a tactical display for public service events, RACES, ARES, or SAR.  You don't necessarily need to be able to transmit those objects to others over RF or the internet.  I often create private objects that show repeaters or places of interest even when not doing events.  Being able to plot the positions of resources that don't have a tracker on them is a very useful feature of APRS clients.


> 2. Are Aloha circles meaningful to Internet-only clients?

No.  Only meaningful if using RF.  Xastir for instance doesn't display any Aloha circle if your only interface is on the internet.
