Er, do you have a reference for what such a beast should be doing?
Kernel smoothing methods generally rely quite heavily on having a
continuous distribution (for density estimates) or having a continuous
x distribution and something on the y axis that allows taking weighted
avereages (for nonparametric regression type problems).
