Start KDE with different config directory

[Armelius Cameron]

Hello, 
Is it possible for KDE to use different config directory other than ~/.kde ? 

Let's say I have different computers or test machines that not necessary runs 
the same KDE version (e.g different Fedora releases), or just want different KDE 
setup on those machines. I want all the machine to mount the same home 
directory from NFS server so that I have access to all my files, but I want the 
different machines to use different KDE config directory: e.g. ~/.kde_machine1, 
~/.kde_machine2, etc. If this is possible, how do I do it ? 

Thanks.
