Hmm, so how do we find out? Maybe there are some chemicals that react differently to different types of plastic, and we could use them on the cases (e.g. turpentine will melt some kinds, but not others).

It sounds like jd and Damion are in the know. What do you think we should do? Does SkiDragon's suggestion sound about right?

The community needs this sort of info! We could add it to the knowledge base for everyone to see.
