Good question.

I should say that it will be allowed after a virtual host specification.

For example, it will be OK to do something like:

     http://foo.com/x/y/++vh++http:spam.com/++skin++ZopeTop/a/b

Note that the skin specification comes at the beginning of a the
virtual path.

Also note that virtual hosts can be used to hide the skin specification.
For example, assuming that the server rewrote:

   http://spam.com/whatever.....

to:

   http://foo.com/++skin++spam/++vh++http:spam.com/whatever.....

then you would be arranging for the spam.com virtual host to use the
spam skin, without the ++skin++ business showing up in the part of the url that
people saw.

P.S. A nice little project for someone would be to add basic URL rewriting
      to the server so that we could do this sort of virtual hosting with
      zope alone. I imagine that the rewrite rules would be provided via
      ZConfig directives.
