[Zope] import folder at other place than root

Is it possible and how to change the folder that the Zope interface use for importing zexp files? I "host" friends on my Zope site, but I can't let them have access to my import folder which is in C:\Program\Zopesite\import At the moment my friends have to email me their zexp files, if they for example want to upload something they've been working on locally. Can I not edit the line where the Zope source code says that it expects zexp files from. Ex. From: importfolder = C:\Program\Zopesite\import To: importfolder = D:\otherdomain\or\host\folder Or: importfolder = "http://www.hostfriends.com/zopeimport" Ideas?
