Much will probably depend on whether they will be part of the GNOME 
Desktop or not:

1. If they are going to be part of GNOME, I think that GDM only needs 
to provide a userfriendly way to start them

2. If they are not going to be part of the GNOME Desktop, I think 
that it would be odd to have some accessibility feature during the 
GDM session, but not during the subsequent GNOME session. I am saying 
this because I am assuming the following: the normal use of GDM is in 
conjunction with the GNOME Desktop (even if it also works with other 
Desktop environments). If this correct?


To 1: For this, I would say that bug 443873 and bug 463713 should be 
considered.

To 2: Otherwise, it would probably make sense to automatically 
activate in the GNOME session, the a11y features that the user 
activated during the GDM session (I think that there is already a bug 
filed for this, but I cannot find it anymore).

Yes, I am still interested in something similar to bug 463713. But I 
think that I will first try to enhance the dwellmouselistener.c code 
to add the killing of the app started by a pointer gesture (as we 
discussed few weeks ago). Is there any documentation about the 
dwellmouselistener.c code beside the few comments within the code 
itself?

If you want to discuss about any other enhancements, please feel free to do so.

Is there any place where I can learn more about what is being done?
