MapServer serves WorldMap data to NetMorph clients. You might not need this, because NetMorph clients also can serve as a MapServer. But, typically, in a classroom, MapServer will run on teacher's machine. It is convenient for administration. You can see/collect all students' projects from MapServer. MapServer can be used for sharing maps in Internet. Default server is running at:http://swikis.ddo.jp:8823/NetMorphMapServer In a NetMorph client, if you set "map from internet" to on, you can share your world with others via Internet. To run the server, just pick the NetMorph Server setting morph.
