Yes, you will declare a projection under the MAP object, and that will 
be the output projection. THen you'll define a projection for each 
layer, and those will be the input projections of the data being read. 
Mapserver will convert the incoming data to the output projection, then 
render the output image, so the data will end up nicely integrated.
