Bobb,

What are you trying to zoom? the image or the client?

If it is the client then how is mapserver on the server supposed to tell 
the client it needs to zoom? You have to query the server to get the 
bbox then make the client zoom appropriately.

For the image, assuming you want a static image showing the parcel, then 
I would write a php/python/perl script the you pass the PIN to and it 
does the work to figure out the extents and return the image.
