hash can be smoked in a pipe/bong, a joint with or without weed, hot knifed, or tee-pe'ed (hee hee). at least, that's the only ways i've tried it.
hot knifing is the best, esp if you have a "shooter" (cut the bottom out of a pop bottle). you just need a couple of knives, a torch or a stove. let the blades get as hot as possible, pick up your little balls of hash with one knife, touch the other and toke baby toke.
enjoy!
