Maybe we could use not a plug-in, but a shared library, that is only 
called when present. What do you think, Pupeno?

With a shared library, we would have this problem only if we change the 
interface, which should happen quite seldom if we design it properly, and 
we could make alll changes backwards-compatible.

It shouldn't handle them.

The plug-in / shared library will just forward the informaton to ATK, 
which is then forwarding it via Corba to the AT-SPI rtegistry, which is 
then forwarding it to the clients.
