    status = XGrabPointer(dsp, w, True, KeyPressMask | ButtonPressMask,
                  GrabModeAsync, GrabModeAsync, None, mycursor,
                  CurrentTime);

It is not legal to pass KeyPressMask as part of the event mask to
XGrabPointer.  See Xlib, sections 7.4 and 8.1.
    
    Now:
        if app runs on panterra & displays on panterra:0 this works.

You probably have bug compatibility mode set on panterra (i.e. via 'xset
bc').
    
    In a related aside, is it possible to use XListHosts(), XRemoveHosts() and
    XAddHosts() in a similar fashion?

XListHosts should work just fine.  XRemoveHost[s] and XAddHost[s] require
that the server be on the same host as the client process.
