language chooser in GDM.. auto-reload gdm and language flags?

[Joao Clemente <jpcl rnl ist utl pt>]

I was very glad to see a way to choose a language in GDM (I was using 
kdm up till now) as my system has users with different language 
preferences...

I wonder if it would be simple to add two features to gdm language 
choosing ability...

a) To reload gdm after after a language choice has been taken:
 - Users would see gdm already in the wanted language and follow the 
login procedure with that language...
This seem to be (theoretically) simple, as I have the feeling that gdm 
reloads when we're configuring it's looks (like standart vs grafical 
chooser). So, if there is already implemented a way to reload gdm...

b) Display available language choices as flags in main display..
 - Just like the "list users" feature, but for languages...
 This one combined with the above, one would click the flag, set the 
LANG and whatever variables and reload gdm into the desired language...


What do you think? How hard would it be to add these features? Is it 
doable or it would require a major-rewrite?

Thanks
