– Tremendous demand: 10,000 students joined in 6 weeks!
– Persistent, heavy usage indicates a change in behavior away from p2p
– Frequency of RIAA compliance letters has dropped dramatically
– 90% of all downloads delivered within the network – tremendous bandwidth savings

Lessons Learned
positive student response validates service model
– in discussion with over 100 schools
– enhancements and local content under discussion
caching is even more critical then we thought
– every school has expressed interest
– we are working with IBM to scale the program
collaboration with University on all aspects of rollout is critical to success
– from student government to the IT departments
