I've had developers try to do the develop-and-test-on-different-boxes thing. I've not seen it be really productive. Theory has it that KDE's KIO should make it transparent to KDE apps, but even then, I'm not convinced it's a good idea.

Better, in my experience, is use an X server (such as Exceed) or remote-desktop (such as VNC) to really work on the box you want to test on. Nothing says "headache" like banging your head against the wall for an hour or two only to realise that you missed a step (such as copying the file to the right place, or testing on the wrong machine).

There just are so many more issues when dealing cross-machine. It's far better to avoid it, so you can concentrate on the actual task, rather than the environment. My 2 cents, anyway.
