Hello, Pinakle,

Microsoft Live Labs shut down in 2010 and Microsoft Expression are the current guardians of Seadragon AJAX, although I do not believe that there is any active Seadragon AJAX development going on within the Microsoft Expression organization.

I am not a developer and not a Microsoft employee, but a resource that might be of use to you in understanding Seadragon AJAX's coordinate system can be found here: Seadragon Coordinate System Tutorial

Here are some possibly related discussions here on Get Satisfaction:
Find real distance in pixels between two points
Mouseover events in the Seadragon Ajax viewer?
Seadragon AJAX Overlay positioned way out of window

...

Hopefully the links above will be useful to you.

In the longer term, however, I would encourage you to keep your ears tuned for news of Bing's new Read/Write World project which I am hoping to see enter Beta in 2012.

Their RML viewer (built with CSS3:3D, HTML5 Canvas, and WebGL) aims to open Deep Zoom Images, Deep Zoom Collections, panoramas, videos, audio, etc. so their organization is the most likely to be actively developing new code using Seadragon AJAX this year. They have also said that they plan to open source their viewer.

I have gathered some sneak peeks from last year at http://bit.ly/readwriteworld
