Problem statement:  files are mostly non compatible or non comprehendible across the
                    operating systems or system architectures(including different
                    OS supported on the same architecture!!).            


                    ...also given the context refer to various standards or schema envisaged
                    in the document referred below viz. projects.pdf.


Opportunity  a :   on the line of front-page publishing and front-page extension
               authentication of usage of pgp kind of authentication mechanism
               would be a viable option.

opportunity  b:    log of hosts (mac-id,processor-id ...etc) accessing the portal-lun
                    or the storage-space of the web-url
    
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.
