If both desktop environments are built to install to different locations, can the desktops coexist peacefully or will there be problems? I know Trinity is supposed to coexist peacefully with KDE 4 so why not KDE 3 too?

Has anybody successfuly tried this?

I ask because I need to test my packages on a real machine after testing in a virtual machine. My only candidates for this testing have KDE 3.5.10 installed. I want to know ahead of time what kind of problems I might or will experience.

Thanks!
