Opportunity: An option or interface to prevent or alert any kind of non-secure 
             authentication mechanisms over internet say without https ...say
             a lock or a indicator as part of the browser , similarlly ...an
             interface on the above lines to prevent non https or non-secure 
             surfing ...prevent phising etc.

 
             Given the context and in conjuction with above a handshake based
             protocol at network driver level that takes cares of all external
             communications ...hence translating at the port level to would be
             a more ideal proposition ...for more information refer to the
             document as referred below


             Also all data transmissions and interaction with a client and server 
             in the context of www or internet ...what is termed or nomenclated
             or christined or comparable or interpretable as a SESSION should be
             conducted under expirable state URL's viz. using the protocol https
             or ssh sessions ...thus the intermediary access points or those that
             are visible in firewalls-proxies-routers...viz. trail of the users
             using the medium should not be able to exploit or miss-used(phising,
             hacking ...etc ).


Note: The above problem statement having been encountered in various scenarios
      and detailed in various 'Proof of concepts' as mentioned in 
      'http://uk.geocities.com/ravivenkatus/projects.pdf' ....apply appropriate
      'use-case' modeling, rationalize and arrive at a workable and feasible 
       solution both commercially and techinically viable.
