Well, it's pretty clear that this idea has a considerable amount of merit to it.
@Fenix: Not only that, but more powerful, to boot. =P Pre-tagging would be nice, as well, now that you mention it.
Fallen : That's a good point. However, it should also be noted in the wiki article that different materials are used for different purposes. An example given is that an aluminum liner (the cone you spoke of) is used when the target surface is concrete.
