    I'm putting this in my .plan, and will eventually work on it unless
    someone points me at a past discussion that showed there were major
    technical obstacles to this.

    I think I could manage inside /usr/ports/Mk:

    * create an update-vcats that works in all of portsdir,
      portsdir/category and portsdir/category/port
    * maintain a list of names of virtual categories in a make variable
    * create symlinks in the virtual categories this port lists in
      CATEGORIES
    * delete symlinks to this port from other virtual categories if any
    
    But I'm quite concerned about the changes needed to make things like
    the package building cluster or make index aware of this. It looks
    like it would have quite far reaching consequences.  Kris?
