There is a maximum of 50 classes per Layer. You'll have to change 
MS_MAXCLASSES in map.h to whatever value you want, then
recompile mapserver.

It's possible. The trick is to use a symbol for displaying lines. With the 
use of a symbol it's possible to use the size-paramter for changing the 
thickness of a line.

For example you can define a simple circle symbol in your symbol-file

SYMBOL
         name "circle"
         TYPE ellipse
         FILLED true
         POINTS
                 1 1
         END
END

Within the class of your line-layer your referencing the symbol

CLASS
         SYMBOL 'circle'
         SIZE 14
         NAME '...'
         EXPRESSION /./
END

Something like that.

Oliver
