My process is pretty close to darkside's. Add Knox gelatin to room temp water in a pyrex measuring cup. Bloom for 20 minutes covered. Nuke until that first bubble breaks the surface. Add to cold beer (I add it to the primary since I ferment in a keg). After 24 hours, I rack off into a pair of serving kegs. A little sediment makes it over to the serving kegs, but not much. That gets stirred up when I move the kegs from cold storage to the serving kegerator, but it settles out pretty fast. Beer is brilliantly clear.
