MotoTRBO can do it. You don't need to know where is anyone, you only have to 
call him and his radio will begin to ring.
I can also confirm that is possible to connect together the two worlds: 
MotoTRBO and APRS. If you have a MotoTRBO server (like could be TRBOnet) you 
can plot the waypoints of all the TRBO users on APRS.fi and is also possible 
to exchange the messages between the two networks with a simple gateway that 
could be developed.
TRBOnet uses SQLServer lite to store all the informations regarding the 
MOTOROLA network so I guess that it's possible to manipulate these 
informations for our APRS' needs.

At my office I've done a study on this project for the civil protection:
in Italy we have the volunteers that often use the ARPS and the 
"non-volunteers operators" that use the MotoTRBO. My idea was to connect 
together the two networks, but unfortunately it's remained only an idea: no 
funds !
