Hi Nicholas...
Most people I surveyed (including myself) use the terminal's scrollback
instead of screen/tmux history. Not a very statistically relevant sample,
but these are all seasoned sysadmins coming from different backgrounds, so
I suppose there is good demand for such feature.
That works perfectly in screen, and it would be great if we have both
options for scrollback in the terminal and tmux history to satisfy all
tastes :)
Thanks a bunch.

Cloud computing makes use of virtualization - but cloud computing
also focuses on allowing computing to be delivered as a service.
