This is an interesting approach. We would only use a small part fo the AT-SPI 
functionality, so we could have some very simple DBUS-based fallback solution 
if ATSPI is not installed (without claiming to fork AT-SPI itself).

The deamon would not need to be bidirectional, because we can use the Qt-ATK 
bridge for the other direction. And it would not need to bridge the whole 
AT-SPI functionality to DBUS, only the few functions that we need.

I agree, but some of the applications already exist as C++ code.
