Expanding site tree

Dear all,

I have put a demonstration expanding site tree (a la
Windows Explorer) on the site at

http://www.paneris.co.uk/system/expander2.html

It is written in Javascript and is nicked from

http://www.dannyg.com/javascript/ol2/

It is generated from mcmeric (TimP's local machine
which has a copy of Paneris on it). It has 2700 entries
(files and directories, not including "control" pages
which are generated automatically, such as index.htmls
- or is that indexes.html? )
of which 2300 are under partners. It is 260K or so and
is unuseable for practical purposes because it has to
reload the page each time (even from cache this is a non-trivial
amount of time) and them go through printing out one line
for each entry depending on your cookie.

I haven't tried the DHTML version yet, which will still
be a large file (over 200K) but might be faster in use
'cos once the page is loaded, that's it. The main problem,
though, is loading 260K in one go whether you want to or not.

What we want to do is only load one directory's worth of
data at a time, and display it in the correct place in
the tree display. We could do this with Java and maybe
DHTML, but does anyone have any other ideas? Will LDAP
help us here (at the cost of restricting our users even
further?).

Thoughts?
