Opportunity:  Exploiting the Tape devices used in Backup,
                    for data recording ....say kind of video casette recorder,Cam coders,
                    Video survialance devices

   
                    There are several light-weight backup tape drive's with
                    varying capacities ....DLT & DAT ...viz DLT/LTO based tapes supporting
                    upto capacities in excess of x00 GB (Giga Bytes) and Dat based tapes
                    supporting anywhere between 40 to x0 GB(Giga Bytes)

                    with several formats and techniques(data compression) around for 
                    storing data on tape's ...one may refer to protocols or standards
                    that are in vogue ....efficiency ...also refer to the document mentioned
                    below.

                    with data I/O i.e. read write capacities running upto XX(say 40) GB
                    per sec 

                    These drive's make a good sense to be shipped or bundled or embedded
                    or retailed as independent portable drives pluggable with Cam coders,
                    Video survialance devices and other similar purposes.


                    When making these devices as a pluggable portable devices interface's
                    using fibre-optic cable for data transfer's between devices 

                    or a RF supported devices(Tape drives data recorders ...that recored
                    data recieved via RF) ....with range dependent on the capabilities
                    of a transmitter (WLL, WIFI,GSM,ATM ...any of these protocols can be
                    exploited) 


Opportunity : Given that in most use-case scenario's ...usage of tape-drive's ...tape based device's
              innovative ...extensions to tape appliance's/libraries

              a) supplented with ample cache memory ...so that once the buffer is filled is flushed to tape,
                 given the nature of a tape ...sequential, contagious in nature.

                 ability to leverage standard utilities shipped on any OS
                 eg: unix (cp ,find directly writing to the device handle) utilities on the tape

              Interface's for access the tape-media
              -------------------------------------

              b) ability to bundle dfs/nfs daemons for remote mountability...in above conjuction such that data
                 can be pushed flushed to the device over or across a network

                 flexibility of piping the data to tape ...client driven or server-driven, ability to use reliabilly
                 ...crc...or other validation should it be required.

              c) to be noted when or where using a such a device on a SAN switch or router's ...while device's
                 not endowed with as in a) ...should be able to leverage cache memory in switch's or router's
                 as envisaged in a).

                 address the issuee ...as envisible from b) ?? ...if lun visibility ?? ...etc?? the myopia ability
                 to pipe the data from client host participating in a SAN fabric to a tape appliance or library.

 
              d) further to b) ...a tape-library with embedded OS.

                 Innovative solution to replication ...dynamic synchoronization of file-systems or system-states.
                 a client-sever daemon's ...with a daemon or code ...that push's data into a tape-medium.
         
                 marketable product variations ...synchronizable as cachefs or just pull data to be backedup
                 using plan cron kind of job or task scheduler ...from all the hosts.
                

                                   
            
 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
       http://ravishankarkv.tripod.com/projects.pdf
        ....apply appropriate
      'use-case' modeling, rationalize and arrive at a workable and feasible 
       solution both commercially and techinically viable.
