I don't know. Should I? :-) As far as i can focus on the problem as a 
not-programmer and a just-web-author there are 3 possibilities:

1 showing one applet twice (or thrice) (the Browser could simply "copy"
   the "look" of the "area". Reaction on Input is shown thrice.)
2 having the applet thrice on the page (just as if it was 3 times in the
   HTML-Source)
3 saying "this only works for ul, p, div,..." in the specs and waiting
   for ideas to appear later.

My Idea was to have an "original" and a "copy". Of course those things 
have to deal with the original. Sorry, but i don't know DOM good enough 
to understand the problem.

That's what i don't want to. Things like the Naviation belong to the 
HTML-Code. This works with all UAs. Solutions that are not compatible 
with former standards (or Web Culture) are not acceptable for me as author.

In some. Maybe. But showing "where am i" and "where can i go" is an 
essential part of web documents and other techniques are not commonly 
supported. Copying with CSS could enhance diplaying on supporting 
browsers (and only on the media where it makes sense) while not 
affecting older browsers and other media.

Spoken from an authors point of view: Display-Property allows to display 
elements 0 times and 1 time. Why not 2 times, 3 times,...?
