I think it depends on what your intended use is. For instance, you could
do something like this:

    (defun bindings-for (key)
      (let ((seen nil)
            (bindings nil))
        (dolist (buffer (buffer-list))
          (with-current-buffer buffer
            (unless (memq major-mode seen)
              (push major-mode seen)
              (push (cons major-mode (key-binding key))
                    bindings))))
        bindings))

    (pp (bindings-for (kbd "C-j")))

This will show you an alist mapping major mode names to the command
bound to C-j in some active buffer of that mode.

Unfortunately, this is far from perfect. The binding could well be
associated with a minor mode rather than a major mode, but it shows the
major mode's name anyway. And different `foo-mode' buffers could have
different bindings for the same key, but it assumes they're all the
same.

I don't know a way to get a really definitive look at "what's bound
where by whom", but hopefully someone else will chime in.
