Immersion Corporation has a series of products that are based on this
idea, though they are smaller than what you are describing (desktop
range).  I don't have all the details with me, but the highest 
resolution system they have is called the "Probe-MD".

You can reach them at (415) 960-6882.

[I have no connection with Immersion Corp. except as a potential
customer who has been impressed with their technical support 
*before* the sale.]
