maybe by an `switch-to-buffer-function' but i'm not sure...
I wrote in another posting that switch-to-buffer was one of the most
important advices in ECB; this is not correct - the advice of `display-buffer'
is at least equally important because it is needed to display all
stuff like help-buffers etc. automatically in the compile-window.

Here is small comment from ecb-layout.el:

;; This advice is the heart of the mechanism which displays all buffer in the
;; compile-window if they are are "compilation-buffers" in the sense of
;; `ecb-compilation-buffer-p'!
;; We do not use `display-buffer-function' but we just handle it within the
;; advice, because otherwise we would have to implement all window-choosing
;; for ourself and with our advice we just "restrict" the windows
;; `display-buffer' can use (by setting the not choosable windows temporarly
;; dedicated) but the real choosing-task is done by the function
;; itself - this is much better and smarter than implementing the whole stuff.

So displaying some buffers in certain windows automatically is very important
for a tool like ECB...of course there are hooks like `display-buffer-function'
which could be used instead of an advice but as described above (see the comment)
this implies to reimplement all standard window-choosing-stuff again which
is a bad idea and superfluous...

So what i'm still missing in the core-functionality of Emacs is a good
and smart concept to 'redirect' displaying certain buffer to certain windows.
