I just saw the neat API V3 Geometry Library

http://code.google.com/apis/maps/documentation/javascript/geometry.html

The documentation seems a little thin right now.  Some questions:
- What units do computeLength and computeDistanceBetween return their
results in?
(I assumed meters, and that loooks to be correct)
- Is there anyway to change those units?

- Does computeLength take a "path" an array of latlng objects (it
doesn't seem to, how do we use it?
It says this: You may instead use computeLength() to calculate the
length of a given path if you have several locations

- Does computeArea take a path? Will it work on a google.maps.Polygon?

The examples don't include the length or area methods.

  Thanks,
  Larry
