Chris,

I think this was already recently answered here on the list.  The short answer
is that Shapelib supports ArcZ files just fine, and you can use them with
MapServer through OGR.  However, the high efficiency version of shapelib
that was integrated into MapServer some time ago does not included support for
3D or 4D shapefiles.  It could be implemented fairly easily if someone was
sufficiently motivated (assume we just want to discard the Z or M values).

Best regards,
