As much as I hate to suggest it, you may be forced to hack the code in lib/python/ZPublisher/HTTPRequest.py that determines what the BASE variable should be... or switch to using a more

What are the implications of doing this? Can I just hard code in my vitual address and everything should work fine?

If it were _me_, I'd do the following, to avoid having to hack the distributed Zope code (which will be a pain when you later want to upgrade to a new version): 1) In your _top_ level Folder, define a property called base_url, with a value that reflects your alias to the top level zope folder. 2) In places where you need hyperlinks, instead of using BASE0, use a construct like: <a href="<!--#var base_url-->/foo/bar/etc">a link</a> This way, you dont have to hack the code, the links should look right and if your base_url changes, you only need to change one property to fix the entire site. The drawback, of course, is that you won't be able to use relative urls in your hrefs (because the browser would prepend the contents of the base tag), but this is usually not a big problem in practice.
