[Zope-CMF] LocalFS and IEeditor...

[Paul Everitt]

First, thanks for posting that link!  We need to help him get into the 
CMF.  Have you ever corresponded with him?

Second, have you considered changing the tree slightly to request the 
data out of band of the page, perhaps using XmlHttpRequest?  If you 
could put a server-side python script and page template combo to 
generate a mound of xml -- and even better, cache it -- it might lead to 
  a better experience.

Still, this is a pretty serious refactoring...I outta speak with code on 
this one. :^)

Can you send me a direct note to talk about what you've done?
