Dear Roger:

(1)  Many thanks for your msg (ATTACHMENT I).

(2)  YES, I am very glad to see many of our electronic colleagues are now
     contacting each other around the world.

     This is the sure and practical way to foster friendship, trust and peace
     among them -- which is the very basic goal of our GLOSAS.

     Thanks a lot for your collaborative effort!!

(3)  Thanks also for your reply comments (ATTACHMENT II).

(4)  During my visit to Renaissance Center in Dickson, TN on 3/15th, I
     visited your web site <http://www.teched.org/starlink> with T1 line at
     1.5 Mbps -- I tried both 20 K and 220 K bps bandwidth.

     I did not encounter any buffering interruption as I reported in my
     previous listserve distribution "Exciting show on low-cost distance
     learning by Roger Boston et al. -February 20, 2000" at
     <http://www.kagawa-jc.ac.jp/~steve/global-univ-2000.html>.  The
     interruption occurred when I tried with my 56 Kbps dial-up modem.

     This means that we now definitely need broadband Internet even at
     everybody's desktop in remote/rural areas!!

Dear Fadia:

(5)  Pls visit <http://www.corbisimages.com/pano/default.asp> and click Jumbo
     to view 360 degree panoramics.

     Although this is not streaming audio/video, you may use the same
     technique for the 360 degree panoramic view of your rotunda which I
     suggested in my previous msg.

     This panorama shows in almost 2/3 of my 17 inch computer screen.

          I am viewing this with my PowerMac and QuickTime, but I am sure
          that you can view it with your Window 98, too -- it is said that,
          because of this QuickTime technology, PowerMac has an edge over
          Window machine in multimedia field.

Best, Tak

Subject: Nice Job!

David word from STARLINK is that your segment and John Hibbs were really
well received yesterday, overall I think we did very well, and wanted to
thank you! for the nice effort.

Will write Colette and the others too shortly.

Tak you must feel good, to see some collaborative fruits continue to
unfold from the great Tent you have pitched across this planet over the
past few years -- see how those of us who have gathered under that
canvass now continue with this work?

By the way I may have this up online by tonight at

The modem stream you listened to / watched was coded at only 20K bandwidth!

this was a SATELLITE ONLY event.
I, as an afterthought, decided to offer this program as a streamed media
presentation to the web as slow and fast speeds for comparison purposes.

If we were to offer this same program as an INTERNET event, and to small
audiences, I would have handled the visuals as separate web pages, controlled
by the audio stream and changing at the proper moment in the presentation,
also provided for interactivity through
(a)  Keyboard live chat
(b) Multiuser audio talking room

These methods I am prepared to show at the next workshop I do for at Manila
or this May at Manaus.

==> TCPIP provides alternate paths, sometimes much better, when you stop and
restart the troublesome stream
== > the modem stream should play instantly and with no buffering, needing
only a true 20K of bandwidth.
==> the 220K high speed and visually CLEAR version requires a true and
uninterrupted 220K of useable bandwidth.

Oh yes!
And that is why I decided to show such promise, by streaming this Starlink
event.  So that more would be aware of tis coming option.

Which file do you want?
the 20K MODEM version is      16 megabytes.
the 220K high speed version is 166 megabytes

I can arrange for you to download either.

Already figured out.
You will see in action at Manaus, or in Manila, which ever happens first :)

Not till they saw what you have just seen did it occur to them in such
dramatic way, that the high costs of the past will soon be distant memories,
now that we have new and emerging options.

I will help Alex with this.
