Challenge and Opportunity
A virtual meeting created an opportunity to:
• Use and experiment with video technologies
• Showcase the capabilities of high-performance networking
• Work together with our member community to make it all happen

Statistics
Over 90 individuals presented
Out of 36 planned track sessions for Austin, 22 were presented virtually
Some sessions had higher attendance than similar sessions at in-person meetings
We received 7,494 unique visitors to the VIMM website
105 respondents to our survey, normally we get around 30
![Page 9: VIMM Follow-On Opportunities and Plans Ted Hanss 29 November 2001](https://reader036.vdocument.in/reader036/viewer/2022062408/56649e595503460f94b52d82/html5/thumbnails/9.jpg)
Positive User Feedback
“Being able to attend without leaving my office.”
“People who weren’t planning to travel to Austin were able to participate.”
“Being able to hop between sessions or view multiple sessions simultaneously.”
“Having archived streams so I can see the sessions I missed.”
![Page 10: VIMM Follow-On Opportunities and Plans Ted Hanss 29 November 2001](https://reader036.vdocument.in/reader036/viewer/2022062408/56649e595503460f94b52d82/html5/thumbnails/10.jpg)
Positive User Feedback, cont.
“The VIMM demonstrated that using video-conferencing technologies to share critical information can be done.”
![Page 11: VIMM Follow-On Opportunities and Plans Ted Hanss 29 November 2001](https://reader036.vdocument.in/reader036/viewer/2022062408/56649e595503460f94b52d82/html5/thumbnails/11.jpg)
Negative User Feedback
No way to have a virtual glass of scotch with colleagues.”
“Interruptions/distractions resulting from normal office demands.”
“Please don’t do this again. Anyone who expects that users will sit and watch TV for multiple days as a replacement for a real conference is out of their minds.”

Technical Debrief
Consensus that overall it went well
Some network problems
Audio problems
Inconsistency in quality of presenters
No floor control for Q&A
Difficulty in measuring audience
TV and netcasting are different, doing both simultaneously is hard
![Page 13: VIMM Follow-On Opportunities and Plans Ted Hanss 29 November 2001](https://reader036.vdocument.in/reader036/viewer/2022062408/56649e595503460f94b52d82/html5/thumbnails/13.jpg)

What’s Next?
Use the VIMM as a model for other events.
Monthly virtual meetings will continue on various topics (initially, Middleware).
Alternate virtual and in-person meetings.
The Commons will offer a suite of services that will allow Internet2 community to host their own virtual meetings.
Best practices and VIMM Cookbook will be published.

A Problem to Solve
As a community we use several, mostly incompatible, videoconferencing technologies
• H.323• Access Grid• VRVS (Virtual Room Videoconferencing System)
• MPEG1 & 2• DV over Firewire• HDTV• …

Approach
Share information about recommended uses
• Decision tree: room-based vs. desktop-based, video quality levels, multicast vs. unicast, …
Point people to current implementations
Facilitate development and deployment projects

Challenges
Funding models
Hitting the right balance of offering stable technologies that work and continuing the exploration efforts
Authentication, authorization, and privacy services (VidMid work areas)
User interface issues
Finding more content

User Interface Issues
What should the Commons “front door” look like?

An opportunity
Partner with the ResearchChannel to get more content, e.g., by getting academic conferences to use Commons technology in their meetings

Corporate Memory: a big question

Smaller Questions
How do people work in small teams or in research lab or in classroom?
How can we work to ensure collaboration is Any Time as well as Real Time?
How to we plan for the long term as well as the immediate or short term?
How can we get the most bang for the buck?
Who can we engage to partner in this activity/research project?
