ATM, there is a way to use tnt for anyone: Using a dispenser. That might not be the "everyone" your looking for, since you'd need an engineer every time you'd want to place TNT in a new place, or use a tnt minecart shot from a dispenser with tracks leading to your new place, but hey, that's already pretty good, besides, TNT doesnt break blocks, what do you use it for? Attacking? Cannoning?
