What you describe is a method of rendering, not a method of smoothing
strokes. Understand that stroke smoothing is a strictly mathematical
concept -- you know that the user drew through certain locations with
a certain pressure, tilt, and speed, and you simplify that set of
points into a smoothed stroke (ie. another set of points). Then you
render the stroke however is appropriate.
To illustrate quite clearly -- Inkscape, a vector drawing program,
includes the kind of smoothing I am talking about.

The problems described by Konstantin are
a) lack of stroke smoothing
b) lack of smooth rendering of the stroke (mainly, jarring 'jumps' in
brush size)
