Tnank you for your reply. 

As you say, kickstart command can filter installation language. But the problem is lacking a easy way to switch to another language which is not installed in the system. 

Once I tried to install Fedora 13 Broffice.org Spin on my desktop. Switching to English is an easy job, nevertheless, Switching to Simplified Chinese is quite hard. Now I do not know how to make GNOME become Chinese interface. Should I reinstall entire GNOME? I have installed Chinese-support group. 

I know separating langpack from GNOME is a difficult and big project. But why does not GNOME pack language files like kde-l10-* for KDE4? It is more flexible. No matter what should be changed in LiveCD, I just hope Desktop Spin LiveCD keeps 700MB CD Size. Maybe Hybrid DVD solution will be more available and accepted by most user.

The appropriate kickstart command to filter exept but french and english is:
%packages --instLangs en:fr:fr_FR:fr-FR
it doesn't  work on EL-5 IIRC and I don't know how it will work with
lang-pack plugin.

The problem was that once the live media is installed, then you don't
have the full set of Fedora packages and you cannot restore the other
locale at this time.

I think an hybrid install/live media with locales stipped is a good
idea that worth some experiments.
