[labnetwork] PVC piping

  This also brings-up the broader technology transfer issue.    One has 
to be careful in providing answers  to technology questions in such open 
forums because the disclosed material may be protected by laws and 
policies, and the disclosure may have unintended consequences.   Of 
course this does not diminish the usefulness of the mtl.mit forum.  All 
the members of the forum have to reminded of its  "totally open" nature  
and the ineffectiveness of the / proprietary and/or confidential /caveats.
