I think we discussed this situation at the sprint last week and decided 
against it.

The idea to use the configured wallpaper falls short in a few ways:
* It can only work with image, but not with animated, marble or whatever 
wallpaper plugin
* it cannot handle the multi screen case.
* we would need to know the activity before kactivity manager is started. 
Especially the login manager cannot know which user will log in, before the 
user logged in.

One of the ideas discussed at the sprint was to define a global theme package 
which is used by all themable elements such as login manager, splash screen, 
etc. etc. This would ensure that all our elements are consistent. What is 
currently still missing would be a plymouth theme being shipped directly by us 
(best would be a ).
