IMHO, this is broken behaviour. If you try to use an URL to locate an
object, the only sane behaviour is to feed this URL to an URL api
(probably in the REQUEST object) to get it mapped to a physical path.

I think this should be done anyway, because of backward compatibility
problems. Really, I think it's ok if at some point we simply say "hey,
now we'll use this new API because that old API was broken and people
relied on the broken behaviour". This is certainly better than pulling
people's rug under their feet. We could then start deprecating the old
API and eventually pull it away, if the arrival of Zope3 doesn't obviate
it anyway :-)

+5 Yes, please!

As the author of ASP404, I'd really like to be able to rely on Zope's
virtual hosting behaviour.

Ideas don't stay in some minds very long because they don't like
solitary confinement.
