[Zope] Autologin

I've got a basic folderish python product where its instances will by default have the View permission switched off, so you get bugger all unless you authenticate yourself. By saving the username and password in Mozilla/IE/... it just requires an Enter touch when the login dialog appears; but I don't even want that to appear. I want it to work like Sourceforge does where it remembers my whole login without any authentication on each visit. What tools/hacks are available to achieve this? -- Peter Bengtsson, http://www.peterbe.com
