you're right. the search database doesn't change much but it's maintained by
someone else. if nothing looks good i'd have to tell him- dude add x/y
column, but something tells me it's not as cool.

sweet. let's see if i get this right-
1 external server does the search and says "show blah blah"
2 my internal server already has a shp as base layer showing all the
geocoded points. i simply create another dbf, do a join and overlay that to
show "blah blah"? (didn't quite get symbolic link. join?)

can a smart wms also help here?
