Place gunpowder, like redstone, which allows you to create a long fuse. It would be nice to have a small mod for this since the only other mod that exists with this feature has way more features than needed (Quark).

Hey Jared! Can you make it light with a dispenser, too?! :D
Creeper interactions would be cool too, you can blow up creepers from a safe distance ;3
The quark mod adds that as wall as placable glowstone dust and countless other features.
