I'm not sure what 'antialiased' output means -- perhaps you mean 'alpha
transparency', perhaps you mean antialiasing within the images, perhaps
you mean something else. Can you clarify?

The answer to the first is, I believe,  "no". WMS spec only allows for
'transparency or no transparency', and MapServer does not implement
alpha transparency output in the WMS images.

The answer to the second is "Sure" -- the images for
http://boston.freemap.in/ are fetched from WMS (by TileCache).
