Let me back that up with an older project. A long-ago buddy of mine was one of the World Health Organization field doctors on the smallpox eradication program in the '70s. The doctors on that project used field terminals with acoustic couplers to occasionally dial into a BBS hosted at the University of Michigan called "Confer"; that was how they reported progress, discussed new techniques, etc.
He was so jazzed by the experience that he ended up founding a company in the mid '80s to build conferencing software; their product (picospan) is still hosting the conversations at the Well.
Note that the answer to the "what about blue lifetime" is at that site: currently, Kodak has materials which hit 40000 hours for red & green, 20000 hours for white, and 10000 hours for blue (this is hours until 1/2 brightness).
