I don't think there is any debate whether a repeater
(more accurately, a D-STAR repeater's gateway system)
can join/connect to a trust server ... and maybe later
connect to a different trust server.

Though - I would question whether the current ICOM
v2 gateway software ... once it  is joined to one 
trust server - will graciously handle connecting
with a *different* trust.  I suspect NOT.
(I have not tried it; I am not sure why I would try it!)


>From the perspective of a D-STAR end-user ...
I wouldn't care that a repeater that I am using
can switch to another (different?!) trust server
in 5 seconds.

What I am interested in is whether I can be accessing
a local Internet connected D-STAR repeater and be able
to communicate with another user of a different but
similarly connected D-STAR repeater - anywhere in the
world (where licensing authorities permit).

Consider this the same a mobile (cell phone) roaming.

You may have a local network of repeaters (today using
a "reflector" to connect band modules over the Internet)
where conversations are repeated within the area.
This would be akin to some of the original (US) cell
phone networks - where you were fine as long as you
were on the network of the carrier you subscribed to.

With systems based on a common trust model (root, realm,
whatever you want to call it) that area can be greatly
expanded.  Expanded to anywhere and by anyone who adopts
(or "registers") with said trust.

Back to the mobile phone analogy: with standards and 
interconnect ... it is possible with my T-Mobile GSM 
phone for me to go to *any* country (that has GSM and 
where T-Mobile has roaming agreements with) and use 
my phone to originate and receive calls, data, etc.


Unless I am totally misunderstanding your postings ...
you are suggesting that each country / group of countries
have their own trust server.  With today's ICOM architecture
each of those would be an island.

I will be in Canada next week.  I would like to talk to
my friends in New England via the D-STAR repeater network.
If all the Canadian systems were registered on and 
connected to a Canadian trust server - I wouldn't 
be able to connect through their repeater(s) to 
mine back home.


>From the perspective of a D-STAR trustee and repeater owner,
ideally it would be great if the architecture provided for
distributed trust servers for the SAME realm ...
much akin to how the root-hint DNS servers are distributed 
around the world.  

Today's ICOM v2 gateway software is not designed to 
operate that way; I know of no way that two standalone
v2 trust servers can sync registered users between their
databases.  In fact - the issue would likely become that
two trust servers may have registered "terminals" that
have the same addresses ... quoting from a movie:
"there can be only one".


To reiterate what I posted before:

Sure - anyone can create a trust server.  And there may
be individual situations that warrant it.   But standalone
D-STAR systems don't bode well for the advancement of 
the mode or the continued development of technologies 
that layer on top of what we can buy today.
