[Zope] Allowing secure 'import' access in zope folder hosting

[Ivo van der Wijk]

Hi All,

We provide zope hosting, both folder based (where people have access
to their own folder, mapped to a domain, and no access to the zope 
server / source / var / import / lib directories) and pure zope hosting
(i.e. an entire own zope server for this customer)

In the folder case, one of our customers whishes to upload his locally
developped site as .zexp to our zope server and import it there.

Can this be done safely? I.e. withouth compromising the other customers
security?

>From some discussions where had on #zope I understand that expecialy 
proxy roles may be a problem which may be fixed by requiring the user
to take ownership.

Would this fix all security issues? Or are there any other unforseen problems?

Would anyone know another solution to achieve the same functionality?
(ftp won't work, as you can't, for example, upload userfolders)

Would it be possible to perform a scan on an xml exports for unwanted 
proxy roles and other security issues?

Thanks,

	Ivo
