I cant answer on the software but I can on the shipping. Looks like the boards should be done here within 48 hours, and then will be dispatched after a small amount of testing to AUS, and me in the US. At least from me, all boards will then be tested again (Not sure how long... suggestions?) and then immediatly shipped out same day via UPS Next Day/2nd Day air [depending on location]. As soon as we know the boards are done, we can give concrete delivery.
I'd sample test say 1/10th of the boards for a few hours on testnet. That'd be my recommendation
That is pretty dangerous (I think). I'm pretty sure all boards need to be tested, the question is for how long. I'm not sure of the failure rate and the test time in general. Perhaps it depends a bit on when the boards arrive. Having them run overnight is not a bad idea. Just my thinking but perhaps some people with experience can help you out. I imagine Barntech and company are the experts here.

I would prefer to test over night as well- but some people would prefer to get something in their hands ASAP. Or accuse me of mining on their boards etc. Maybe Test everyboard for an hour or so.. that should be doable.
