Re: running Gnome apps on an ssh session

Hi Kenny:

Accessibility for remote GNOME apps is still on the roadmap. Because 

the accessibility framework uses CORBA, it works in theory, but in 

practice, the bonobo-activation mechanism which GNOME uses to register 

with the at-spi registry is tied to localhost. So the missing link is a 

remote bonobo-activation; once you have that, the rest should fall into 

place.

So it's a known issue that this doesn't work yet, but making it work, 

though it will require some new code, should not be a big effort.

Here are some technical details:

1) applications load an accessibility bridge at startup, and register 

with the accessibility registry (at-spi-registryd) via 

bonobo-activation. Due to current limitations in bonobo-activation, 

this registry is per-user-host, not per-display.

2) the 'application instance' which is reported to the registry is 

network-transparent, i.e. it could be local or remote. Once the 

registry, or an assistive technology, receives a reference to a remote 

application, it can communicate with it just as though it were local 

(though possibly more slowly).
