Please define exactly what you mean by "good tactical messaging".

Wait, don't need new features, but want something that is actively 
developed?  If it's being developed, there's going to be new features.  
If there's no new features, what's the point of the development?

So, you're using something else to provide message gating for the area?  
Or you're restricting all participants to RF-only communications?

What's the difference between "Internet" and "APRS servers"?  Is there a

"all the maps" is quite a broad statement.  Can you clarify just what 
"all" means to you?  And if they're loaded ahead of time, how do you 
account for updates in the ever-changing mapping landscape?

Personally, I believe that CSV or plain text is much more portable than 
XML, even though the latter is coming up quickly.  And in either case, a 
file is not "paper" unless you've got some good mobile printers to go 
with the application.  "audit trail" may be more what you're after?

Actually, with a bluetooth to serial adapter on the TNC, you can connect 
your smart phone to the TNC/radio if you have a suitably capable APRS 
client on the phone.

PS.  I'm asking for details as I AM actively developing an APRS client 
and would like to migrate it to meet as many people's needs as I can, 
but only if those needs are described to an adequate level of detail.
