Make non-editable region invisible

[NateWeb]

Is there a way to make the non-editable regions invisible to certain user
groups, or all users? My template has a good amount of .net, javascript, and
some flash that cause it to not render well in the editing window. The
editable regions render fine, so I was thinking if I could just show those it
would cause less confusion. Any ideas?

Thanks

I can think of using CSS smartly or serverside includes (f.e. PHP) that contain
only the editable regions.
When using CSS you have to find out what contribute does display and doesn't
display in editing mode.
When using serverside includes, your users have to know the urls's to the
include-pages, maybe you could provide them with an alternative navigation,
thats only for the includes.
