I once tried to make magma waterfalls on either side of my fort's entrance, but I underestimated the speed at witch the pumps would spew lava... Yea I needed to dig a new entrance after that. Although it ended badly, it did get rid of the next few sieges that showed up... and the caravans... and all the new immigrants... COME IN FROM THE OTHER SIDE OF THE MAP YOU IDIOTS!
My only use of pumps prior to that point had been to make the dwarven power generator that RAN the lava pumps, so yeah... next time I attempt that I'm building a bigger lava reservoir... and a few more pumps down there... and actually remembering to hook up those pumps... 
I did the same thing, only I controlled said magma waterfall. Unfortunately, once I turned it on to repel my first gobbo raid (and, unfortunately, a booze laden caravan), I thought it was too awesome to turn off. Then I realized that while my drainage system was rather impressive, magma does not like to move horizontally, causing my drain to back up until it flooded my entrance.
Once I managed to get the mess under control, I noticed that I had somehow set my coke road ON FIRE! Unfortunately, I have yet to figure out how I achieved the dwarven feat (magma+coke construction=nothing happening, I suspect the proper formula is burning object+coke construction=FIRE). I therefore propose that if anyone figures out how to make eternally burning constructions, the ultimate monument to all that is Dwarf would be one that is made out of coke and on fire.
