bridge question and invitation</DIV>
<DIV><BR></DIV>
<DIV><FONT face=Arial size=2>Greetings AG-Tech,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV>I was in a conference yesterday over the NCSA venue Mosaic. I was a
multicast site. There were others that were unicast and I was able to
view their conference just fine. We had a "unicast" PIG in the room and
it was receiving additional unicast streams we did not see on our multicast
session. I thought this venue has a built in unicast/multicast
bridge. I selected unicast and then all the sites were available.
Any ideas? Bad multicast on our end? </DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>Our site is currently being born and we will
be testing this Friday all day. It is listed in the AG Schedule as
Testing Strongly Interacting Quantum Gases. Even if you will not be able
to make the conference on 4.18-4.21, I would really enjoying meeting you via
the Grid and test. </FONT></DIV>

<DIV><FONT face=Arial size=2>Have a great day!</FONT></DIV>
