Hi Guys,

   I came accross a couple of questions while reading the
NeXT Concept document.  I would appreciate if any one can
give me some help.  My questions are listed in the following:

   1] Can a client of a NeXT Step window server be running
      on a remote host?  If this is possible, under which
      document is this capability documented?

   2] Does NeXT Step take advantage of MACH's threading, 
      virtual memory management and messaging facilities?

      Is there any documentation on how application programs
      can benefit from the MACH facilities?

   3] In Concepts, there is an example, illustrating the use 
      of SUPER in Objective-C, in the following way:

      In B.h:

         class B: A {
            .
            .
         }

       In B.m:

         + new 
         {
		B   *bInstance;

		bInstance = [super new];
                    .
                    .
                return bInstance;
           }

       The semantics illustrated above seems to imply that 
       bInstance will be pointing an instance of A since
       "super" causes the invokataion of A's new.

       Will class object B return a structure, which properly
       represents the newly created instance of B, if B has 
       additional instance variables other than A's?

   Thanks in advance for your help.
