Raindeer writes "In an effort to promote its new Cloud based DNS service SKYE, Nominum one of the commercial DNS-software, providers slaundered all open source/freeware DNS packages. It said: "Given all the nasty things that have happened this year, freeware is a recipe for problems, and it's just going to get worse.(....) So, whether it's Eircom in Ireland or a Brazilian ISP that was attacked earlier this year, all of them were using some variant of freeware. Freeware is not akin to malware, but is opening up those customers to problems. " This has the DNS community fuming. Especially when you know Nominum was one of the companies affected by the DNS Cache poisoning problem of last year. Something PowerDNS, MaraDNS and DJBDNS all open source weren't vulnerable too."
There's also a QuotaFolder product for zope, which together with Zope offers exactly what you want. You can see a working setup of all of this at FreeZope
