Lessons learned and status
• In production use in UW Professional Masters Program since 2002
• Other projects – UMass/Galloway, Australia Distance Education,
WWAMI Medical Education
• Multicast networking has been a challenge• Classroom setup especially audio is critical• Deployment in real classes has been critical for
moving the technology forward
