I'm not aware of any means to do this. If you're using PostGIS perhaps there's
a way to use the !BOX! hack in conjunction with some of the analytical

Quoting Paul Ramsey in the link above:
"
the evil "!BOX!" hack: In your data statement, if you compose it thusly:
DATA "the_geom from (select gid,the_geom from thetable where the_geom
&& !BOX!) using unique gid"
When the postgis driver encounters the evil !BOX! it will replace it
with the current mapserver bounding box.
"
What exactly is the status of this demonic !BOX! hack? Is it described somewhere? Is the
"current mapserver bounding box" queryable within MapServer itself?
