They did make great videos!
The voice of Patrick Stewart at the start of the Nebula One launch video still gives me shivers: https://www.youtube.com/watch?v=r4rsEjsomFI
And don't forget back in 2011 with the launch of the company at OSCON with the who's who intro video before the presentation including hardware pr0n https://www.youtube.com/watch?v=3oydzMfFYWM
I also couldn't help, but think that http://opennebula.org/ will be happy for the end of the namespace collision.
Hubris videos aside, Nebula.com carried more than their share of the weight in the first 3 years of OpenStack, and made me believe that OpenCompute wasn't just Facebook. Thank you and best wishes to all who brought NASA Nebula to open source and made OpenStack a reality!
