Coexistence betwend kde3 and kde4

[Leopold Palomo-Avellaneda <leo@alaxarxa.net>]

Hi,

I don't want to install kde3 and kde4 in the same box. 

However, I administrate several boxes and I would like to have some box with 
unstable (kde 4.2.2) and stable (kde 3.5.9) using the same /home for the 
users (ergo .kde)

So, is this possible?

Regards,

Leo
