Could you briefly describe the SOS, and how it would be
integrated with MapServer?  Is this another datasource,
we we read from remote sensors and then plot the results
as point features?  It is another way of publishing MapServer
point data (where mapserver is the server)?  Both?

If the implementation were able to be quite localized to one
module in MapServer, and if it sorts of fits with the mapserver
role of publishing geospatial data on the web, then I don't
think I would mind it living within the mapserver tree.
