Write a custom traversal adapter:

from zope.interface import implementsOnly
from zope.component adapts
from zope.publisher.interfaces.browser import IBrowserRequest
from zope.app.container.interfaces import IContainer
from zope.app.container.traversal import ItemTraverser

class IVirtualHostRoot(IContainer):
    """We assume that the roots of virtual hosts are containers"""

class VirtualHostRootTraverse(ItemTraverser):
    adapts(IVirtualHostRoot, IBrowserRequest)

    def publishTraverse(self, request, name):
        return super(VirtualHostRootTraverse,
self).publishTraverse(request, name)

<adapter factory=".VirtualHostRootTraverse" permission="zope.Public" />
