At-SPI client and server running in different hosts

[Alexander Todorov <atodorov redhat com>]

Hello list,
I am encountering an issue discussed long time ago:
http://mail.gnome.org/archives/gnome-accessibility-list/2005-December/msg00040.html

I need to run AT-SPI server and client on different hosts.

As stated in:
http://mail.gnome.org/archives/gnome-accessibility-list/2005-December/msg00040.html

"So on the server side you must write a small piece of code which does 
exactly this, obtains a reference (IOR) to the at-spi-registry in the 
"usual way", then exports it as a "stringified IOR".

Then on the AT client side, you need to make a small change; instead of 
using the usual bonobo-activation-based method for obtaining a reference 
to the at-spi-registryd Registry, you instead call a piece of code which
reads the string from the server-host and calls orb.string_to_object to 
get a valid IOR from that string.

From there on, everything should work as normal (as long as the client 
always uses this cached IOR for the registry, obtained via this 
alternate means."

What is the present status of this issue?

It has been fixed and I am able to run an application exported to 
another display on the same host and access it via Dogtail.
When I run an application from one host and display it to another host 
it is not accessible. Both a11y and X permissions are setup correctly, 
no firewall, running as root.


Can someone give more details about the above mentioned modifications of 
client and server? Are they needed at present? If so what do I have to 
modify? My program's source code? Is there a work around or an option
to tell a GTK program which IOR (registry) to use?


What is the state of this issue in respect to migrating AT-SPI to D-Bus?
See:
http://www.linux-foundation.org/en/AT-SPI_on_D-Bus
"It would be good to extend AT-SPI to allow accessible remote access to 
applications"

As I understand so far at-spi-registryd is the deamon responsible for 
registering applications. Can I configure my client's registryd to share 
the register resource with the server's registryd?
Where is the documentation on at-spi-registryd? I seem not to find 
anything even on google. Running with --help, -h, -help doesn't work for 
me. No options show.


Any help and/or points in the right direction are most welcome.

Greetings,
Alexander
