As always, it's faster to talk than it is to search, and I found a solution in
svn sandbox, in tv/monsterguard. It "simply" uses an intermediate root page to
declare the VHostMonster.

I looks like this :
In apache configuration :
ProxyPass /app http://localhost:8080/vhost/http/www.example.com/app

In tac file :
# Start code
realm = mysite.MyRealm()
portal = portal.Portal(realm)
portal.registerChecker(checkers.AllowAnonymousAccess(), 
credentials.IAnonymous)
portal.registerChecker(mysite.MyCredChecker())

// Create a small static page, should not be accessed
root = static.Data('This is the private server, not accessible from the
Internet. It hosts <a href="app/">app</a>', 'text/html')
root.putChild('', root)
root.putChild('vhost', vhost.VHostMonsterResource())
root.putChild('app', guard.SessionWrapper(portal,
mindFactory=livepage.LivePage))

// MySite is an appserver.Site
site = mysite.MySite(root)

application = service.Application("mysite")
internet.TCPServer(8080, site).setServiceParent(application)
# END Code

Et voila.
