I also haven't actually been able to figure out exactly what it is that's 
being asked for. Is it something like this?

Say we have a web site in 
/admin/web/.... and we want to have totally different look and feels 
for the web site - different colors, fonts, logos, or whatever.

One way to do that is to put all the looknfeel specific elements into
a folder in, say, /admin, and then wrap the pages in 
<dtml-with lf_foldername>
page contents here
</dtml-with>

or, if the looknfeel folder name is in a variable, 
<dtml-with "_[looknfeel]">
page contents here
</dtml-with>

so say we have

/admin/
       lf_prettycolors/
       lf_prettycolors2/
       lf_plainpages/
       web/ 
           content

inside each of the lf_ folders, you'd have a bunch of standard named
objects, e.g. a dtml method called 'header', another called 'footer', 
maybe properties for 'font1name', 'font1size', 'font2', &c.

when calling the pages in /admin/web, I'm assuming there's a cookie, 
or a form variable, or something, called 'looknfeel', that's set to, 
for example 'lf_plainpages'. 

A page in /admin/web could then look like

  <dtml-with "_[looknfeel]">
  <dtml-var header>
  <font face="<dtml-var font1name>" size="<dtml-var font1size>">Welcome</font>

  body here...

  <dtml-var footer>
  </dtml-with>

and it will pick up header, footer, font1name, and font1size from whichever
folder is named by the looknfeel string.

Obviously there's a lot more you can do here to make this cleaner, and more
managable, but there's a start...
