[Zope] opinions please

hello, i am searching for opinions on a project i am considering. the project is to create a product or script to allow users to email documents into Zope as attachments. then the documents are to be placed in the proper folder according to information in the subject line of the email they rode in on. what i would like to know is, is this possible? if it is, how hard will this be to implement? the other idea was to create a client app where users can drop the document onto a desktop icon and the app uses webDAV to put it into Zope. would this be easier or harder?
