Problem statement:   understanding how a tcp/ip...protocol ...strengths ...weakness

                              packet broadcast ...devices compliance ...reception of data pertaining to only 
                              their destined packets ...understanding of procimous-mode(viz. ability to monitor or
                              recieve and absorb...all packets flowing through the vicinity)

                              tcp/ip ...loopback mode ...ability of two hosts connecting their network-adapters
                              via a loopback cable ..their ability to communicate with out a switch/hub ..as a VPN.

                             Wireless Lan i.e. tcp/ip based or over radio-packet ....strengths ...weakness 
                              ...complaince to  [...requirement or neccesitty of  switch/hub ... for wlan equipped
                              devices to communicate with each other ], given the context ...ability or requirment
                             to regulate ...parsability or access data broadcasted by other devices within a vicinity
                             of device with wlan...broadcast


Opportunity :  WLAN is a supported feature on many mobile and portable computing devices in market place or parlance,

                    using the above ability to create a VPN communication between two devices supporting WLAN
                    for sharing data-services ... by ip-addressing nomenclature [ and encryption] ..say setting up
                    a personal network using  the tcp/ip ...private ip scheming ...say 192.168.xxx.xxx or 10.
                    subnets ...

                   [ tcp/ip loop-back mode ...schema  ...as also kind of  blootooth pairing of devices ]

                    ....given the context and requirement being bandwitdth of spectrum or RF ...amount and speed of
                    data-transfers.
       
                   [  also the possibility of  setting the device as a wifi-server ...as good as wlan router or acess point
                      as many should be providing a interface for setting up their pc/laptop/mobile device in such a mode ]


                   Given the context ...innovative data and services sharable ...between to wireless supporting devices on
                   such a private network [...existing or standard filesharing services ...including SMB ...]

                   ...features to be supported by mobile-OS to take leverage of such a connectivity both in personal computing
                   and corporate computing or mobile-network  ...using the concepts or technologies present in WLL (CSMA / cmda
                   rationalize the context of usage ...primary usage of the PDA MOBILE device), i.e. to juggle between two networks 
                   or network sessions....i.e. optimize the use of the wlan card on a PDA MOBILE....by having two profiles active
                   on the WLAN ...either sleep or save session on the personal network ...idea or requirement simply put is same as
                   the ability to socket multiple IP on NIC in os/computing context ...ability to service on both the networks
                   [...in the above context same as keeping the FM radio in sleep when a call is active]

        ....apply appropriate
      'use-case' modeling, rationalize and arrive at a workable and feasible 
       solution both commercially and techinically viable.
