Ah yes, great point, thanks for the suggestion.

If people who are have been working with each of these areas could send
me their use cases, that would be immensely helpful.  Especially those
people who have been providing their own patches or product and know how
their customers were using them.  I'm certain Cedric and probably Eric
can provide some good justification/motivation for checkpoint restart,
for example, and Kirill and Herbert for virtual servers.

thanks,
