I was wondering the other day if it would be useful to have some ready set-up KDE and release specific development environment with all the required installs and sources ready as virtual machine images?

People could then just load the image in case they had something to add to that particular release without having the need to make an all out investment on what distro and what release they are working on (given it had become a common practice).

I think I would like if I was able to pick any distro/release and run its development environment up and perhaps update some source somewhere to certain version and try something.

Now, I am not sure if it is actually a good, or practical, idea at all. There might be some real need to approximate this, say for instance for storage reasons, etc. I'd really appreciate hearing some reasoning in any direction about this; if for nothing else then to settle my mind about it. I feel kind of foolish here but I have to know.
