I now have standard deviation error circles working to display the calculated positional error. It shows the possible circle error from all the positioning measurements (i.e., the client could be located anywhere in this circle):

This value calculated is the radius of the circle surrounding the position as the center point (the developer just has to draw the circle from this radius). This is updated in the Android API repository on GitHub.

I also have a fancy new website (the wiki is still there as a link) at :
