I completely missed this response.
Still having this issue so going back over this again.
Can you identify which things and where for the items above?
  path_to_folder_containing_the_mount and ID_of_your_mount_point

This is in the zope.conf:

 <zodb_db session>
   mount-point /session_folder
     server blahblah.com:9999
     storage session
     name session
     client session
     var $INSTANCE/var

This is in the zeo.conf:

<filestorage session>
  path $INSTANCE/var/Session.fs

In the ZMI, there are:

/session_folder/      ( a regular folder )
    session_data      ( Transient Object Container )

/session_data_manager ( Session Data Manager )

All the parts seem right but its not working....session writes wind up 
as anonymous transactions in the main ZODB.

Any ideas?
