[Zope] looking for a poor mans' xdrive.com or ibackup.com

[David Meltzer]

hello and thanks for reading this,
i know that zope support webdav.
ibackup.com, a commerical company, offers webdav access for a fee.
i was wondering if someone had written a zope application that could function as a simple webdav
server and a simple user interface to modify it.

i am trying to help a school find a free way to use webdav for the teacher's and student while at
school and at home.
i think that zope should be able to handle this.
so any suggestions or advice?

thanks,
dave
