I'm trying to identify this succulent I got from a friend. It spreads in two ways:

• Sometimes a stalk will tip to the side, and then sprout roots downward to creep along. One of the photos below documents this.
• More often, though, seeds form along the edge of the leaf, drop to the ground, and start new plants.

From my findings so far, the best I can figure is that it's some sort of kalanchoe - but I'm not entirely sure about that.

Other info:

• Leaf parings alternate: one pair will be front and back, and the next will be left and right
• the leaf edges are serrated, and bear a thin red line along them
• I'm growing it inside, in a pot. It loves direct sunlight most of the day, and is thriving near windows
• I water it weekly, allowing it to completely dry between waterings. It seems quite happy with this arrangement.
