AT-SPI/D-Bus integration work needed for GNOME 3.0?

[Willie Walker <William Walker Sun COM>]

Hi All:

As a result of the AT-SPI/D-Bus hackfest held as Sun Ireland last week, 
we think we have a high probability of reaching success for supplanting 
the AT-SPI/CORBA implementation with AT-SPI/D-Bus.  Yeah!  :-)
I have a question about how to handle the transition.  Currently, the 
AT-SPI/CORBA solution is hosted in the GNOME git repository.  The new 
AT-SPI/D-Bus solution is hosted in the freedesktop.org git repository 
and is likely to stay that way.  In addition, to permit the option of 
introducing incompatible API changes, we're planning on adding a '2' to 
the module name (e.g., at-spi2).
What impact does the different git repository and the module name change 
have on the release engineering process?  In particular, what do the 
AT-SPI/D-Bus tarball providers have to do to help make this happen?  For 
example, is a new module proposal needed?  Is an "external dependency" 
now required?  Etc.
Thanks!

Will
