polytrip: can you post a link about that?  i would love to find out who is proposing this.  a google search sends me all over.  if you can remember the site that would very cool. 

also:  hullo nexus!  i have been away from this forum far too long, and missed it.  even though i have never been an avid poster, i certainly read a lot (and learned a lot too).  feels good to be back again.
