[Zope] ExternalFile and ZEO

Hi, I currently use ExternalFiles to store files of my Zope site. My question is : what is the best way to use ExternalFiles in a ZEO environment ??? Should I share the directory containing the files throught NFS, or sync the master server with ZEO clients throught rsync or anything else ??? Thanks for any help, Thierry -- Linux every day, keeps Dr Watson away... http://gpc.sourceforge.net -- http://www.ulthar.net
