I think the point KE5C and G4ULF are trying to make is this:
There is a certain expectation among D-STAR RF users that if they are in range of a D-STAR repeater, that provides gateway services, that they should be able to do callsign routing to any other D-STAR RF user that is in range of a gateway equipped D-STAR repeater. This means that they all need to be on the same "trust server" in the current architecture. As an RF user, I shouldn't need to find out which trust server the local gateway uses (is it on K5TIT/USTRUST or another trust server?). I should simply be able to put the callsign in the UR field, along with the proper RPT1 and RPT2 entries, and make my call.
Having other "trust servers" that don't sync with each other, segments the D-STAR community into cliques -- most of us do not want that, we want a unified D-STAR network.
Personally, I would like to see an improved "trust server" with the following changes:
1. RF users don't need to register to be added to the "routing" tables. The gateway just reports who it hears on the air, and requests routing information for those callsigns it does not know. 2. Internet connected nodes have a strong authentication (gateways, application servers (such as DPLUS and D-EXTRA), reflectors) -- Dongle type users would come into the network through an application server, rather than direct -- then they would be treated like other D-STAR units with callsign routing, etc. 3. A confederated trust server architecture so that regional trust servers sync database entries so that a gateway or application server could ask any trust server for routing information. 4. A bridge to the Icom architecture and a new "short hand" capability where "G" nodes don't need to be entered in RPT2 if the controller sends all traffic to the local gateway.
Until Scott can take the effort to work with K5TIT to get his code tested on their test system and have it talk to the USTRUST it will not be of interest to most repeater/gateway operators. G4ULF has gone to that effort, so I think we will start saying a lot more homebrew repeater/gateways coming on line using his code, once his production beta is complete.

There are 4 European ICOM TRUST servers. You would need permission with them to register your home-made "ICOM compatible" G2 Gateway, same thing with the US. I also have instructions on how to create a NEW ICOM TRUST server. They have created their own ICOM TRUST server, just like K5TIT did. They are pretty active witrh their ICOM TRUST server and they allow registration from anyone that wants to learn. I do not believe that they would deny you registration if you asked them. The Europeans TRUST server groups are very friendly. My dstar "ICOM compatible" G2 Gateway KJ4NHF went live with the European TRUST server a couple of weeks ago. Scott/KI4LKF
