Getting another non BDREN MA in BD will require some site setting up a PingER MA, and making measurements. By the time the site and MA has been identified and the pinger.pl installed I doubt there will be many measurements by the time of the conference with enough time to analyze the results and draw conclusions. On the other hand setting up the Daffodil MA to measure multiple sites in BD is much simpler and quick, so some measurements could be available for analysis before the conference. They may not be as complete as those from multiple MAs but they may provide useful information. To add extra hosts see here.
I ran a script to get potential Bangladeshi web servers that have been seen by Google., We also need to determine if the hosts are on BDREN or another ISP. I looked up BDREN to see which sites are on BDREN at http://www.bdren.net.bd/member.php, and created a spread sheet of hosts in Bangladesh that I can ping that are www servers, are in either edu.bd or ac.bd (I also added known BDREN hosts) together with which hosts are on BDREN and if on BDREN whether the host responding to pings has a RTT of ~ 250ms (i.e. likely to be in Bangladesh).
