The cedet-cscope support just is about invoking cscope.  It is used by 
EDE (file location) and the semantic-symref functions (symbol references.)

It could probably be used for tag lookup, but no-one has written that 
interface yet.

It doesn't use the line interface because the different places from 
which it is called can be for different locations, and possibly 
different cscope dictionaries.  Not insurmountable, obviously, but I 
took the easy route that mimicked GNU Global.

CScope itself has more features than what is used by the CEDET support, 
so for the original question, it depends on if the EDE or Semantic 
features covers what he wants to do.
