IP multicast is a suitable advanced application.-- IP multicast has a proven track record as a success in the traditional I2 university space; it can be just as successful for K20-- It is designed from the get-go to easily scale to support K20+ sized audiences
Opportunities for intensive training of K20 staff and end users are often quite limited, and technology topics compete with non-technical material which must also be covered. Training time can be a real issue.
The best technologies for K12 are those which do NOT require intensive or extensive training for “everyone.” The best applications “just work.”
By sheer luck of the draw, some K20 sites may have older network equipment, or equipment from vendors which poorly supports native IP multicast
Other K20 sites may need to build out better wide area connectivity to take advantage of I2 connectivity (some of our Oregon partners are in the process of deploying their own fiber to our gigapop); 1xT1 or 2xT1 just won’t do it.
-- no multicast via most dialups or third party ISPs (including most DSL and most cable modem providers)-- sourcing content is significantly different from just viewing content-- debugging (can be) non-trivial
