Problem statement :    a dns resolver ...that resolves to a specific ip/host

                       based on time-zone ....implementable ideally dns ...

                       while ip-cast ...NAT is always possible.


Opportunity :  given the advent of virtual office or 24x7 operations or

               some-one represently or being available round the clock ...

               to attend to tend to ....taking into account of time-zone difference
               ...a dns algorithm or a ip-casting based solution that resolves or
               translates into a data-center that is live and fully operational with personal
               who can attend to tend to.

               Thus ...call-center or call-manager or virtual office solutions centric around the 
               concept ...i.e. ability to route traffic as also business taken care by the part
               of office on the globe that is a working-schedule or within business hours

               Dynamic dns ....servicable-ip ....ip-live...timeout...dns...timeouts...
               
               ....potential scope for cname kind of alias for a dns ...with live-period specified

                .....vis...vis...vulnerabilities of  DNS ....cacheing...secondry ....refresh or
                publish rates from primary to ....secondary ....cacheing ...round-rob-in-scheme's

               eg: the jobserve.co.uk as represented in the australia, uk , us and INDIA

Problem Statement: understand analyze VOIP protocol stack ....GPRS based voice networks

                   h.323....NAT ....??? ...complications implications

                   ....ip dailing .... mobile number based dailing?? ....protocols used/ applicable
                   

Opportunity:  simply the stack of application and routing layers for call routing and call management
              over gprs ...context of convergence or myopia of ip-networks and mobile-networks

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