Also helps to keep a Setilog.csv file, which Seti Driver can do.
I use mine with Seti Watch and I have a SetiQ running here also, I keep a cache on each machine with Seti Driver and each connects to Seti Q to send & receive WU's.
If Berkley goes offline for ten days I have enough WU's to keep all my machines running.
I think the most they have been offline at one time was 3 or 4 days, but that would be a long time to be without Work Units.
If you are connecting to a TeAm Queue then that takes care of your WU needs, then it's just a matter of personal preferance.
Of corse if you are running a multiple cpu rig then you can use Seti Driver to run multiple instances of Seti Cli.
