[Zope] CVS/VSS - how are others doing it?

Hello, We taking the first steps towards using zope as an Intranet server. What is the best way to do file repository stuff - CVS/VSS? I know there is ZCVSMixin, however we are (primarily) a windows shop, and use Microsoft VSS. I do use teamdrive, which is able to mount an FTP/WebDav server to a drive letter, which I could then use with VSS, but as far as I know, using FTP/Dav does not preserver object properties. True? If not, and properties can be preserved, are there other issues with this? Thanks - Scott
