I was on the local MBone segment at the NASA base (though a Navy installation) I worked at in the late 90s. It pretty much worked like you would expect, some interesting things that happened: - Multicast frames caused our FDDI switches to reboot, had to filter everywhere those were used - When setting up our local CoffeeCam, we used Multicast video stream -- this would have been accessable from anywhere (which would cause a security incident, no one can know when the Rear Admiral drinks coffee) so we were careful to monitor outbound advertisements and used a low TTL - SDR, VIC, VAT, RAT, and all those other tools for doing multicast stuff worked but were very clunky - NASA TV was broadcast over the MBone and times they would go to break in other broadcasts were continued to stream, I think various cameras were available
