If you use Xft, fonts are loaded by the client side. Usually, they use a cache 
file for the installed fonts for lookup. But you have to regenerate the cache
(e.g. with fontconfig: "ft-cache -v" as root) after installing fonts.
Perhaps if there's no cache (and no write permission to create a cache file in 
the dir of the fonts for the client application), each application has to 
load all the truetype fonts itself?
