Jonathan,
Thanks for the input... is there somewhere you can point me that I
can read about how to do that myself?
Thanks!
If you are looking for info on how to use mount points look in the zope.conf
file in your zope installation which should be in the ...zope/etc
directory.
Google for 'zope mount point' and you will find lots of info as well.

If you have set up the 'virtual' web sites so that they have their own
folder 'tree-structure'
eg.
root
- virtualWebSite1folder
- virtualWebSite1subfolder...
- virtualWebSite2folder
- virtualWebSite2subfolder...
- virtualWebSite3Folder
- virtualWebSite3subfolder...
you can export/import a single folder instead of the entire Data.fs.
Another solution is to set up a mount point (ie. a separate xxx.fs file)
for
each folder.
