How do I add a segment to a path?

Hi everyone,
I have a river network and a point on that network.  I would like to find the segment intersecting with that point and assign it to the IPath interface.  My next step is to continue adding downstream segments to the path until the total reaches a given length.
If my original path is defined as a line feature intersecting with a point, then how do I expand that path to include "downstream" segments?
