I'm posting this again here - hoping that google helps out others. 
MapServer has a metadata keyword named "labelcache_map_edge_buffer". 
Pair this with an integer number of pixels, and you get a map rendered 
with no labels in that buffer.

The only documentation for this "experimental" feature that I can find 
lives here: http://mapserver.gis.umn.edu/download/current/HISTORY.TXT

So, if you want a ten pixel label buffer on your tiles, in MapServer you 
can use

METADATA
     "labelcache_map_edge_buffer" "10"
END

There, documented.
