Determining Physical location of machines

[Kevin Willock <kevin () cipher1 com>]

To further up this question, is there any method of determining the true 
location of a server/user behind a satelite uplink connection? I have 
contemplated some BGP or AS methods but have not formalized any game 
plans. Does anyone have any practical experience in this area?
