Sorry, the 20 units there are 20 user units for the x coordinate of the
rect, not a number of frames.

My example would be equivalent to

  <rect x="0" y="0" width="100" height="100">
    <!-- move 20 units every second -->
    <animate attributeName="x" from="0" to="2000" begin="0s" dur="100s"/>
  </rect>

except that with the SMIL animation I have to stop the animation some
time (because interpolated animations aren't possibly if the animation
is indefinite).

Yes that's how it is. :-)
