Yes it runs locally too, it doesn't really matter whether the server is
remote or on the same machine.
Example, one xterm:
axboe@nelson:/home/axboe/git/fio $ ./fio -S
Another:
axboe@nelson:/home/axboe/git/fio $ ./fio --client localhost null

For sure, or Qt. I think it'd be really cool for various reasons, some
people find it a lot easier to visually see all the options and drop
down menus as opposed to a CLI tool. Also great for demo purposes. Like
iometer - it's a crap tool, but the spedometer thing really works for
demo/show purposes.
