good news is that you dont need to be the machine's original owner to do the RMA. bad news is they dont do advanced RMA or cross-shipping. the quote below is from Kurt on the KNC forum.
edit - bad news is that is still time (and consequently money) lost without being able to hash.

It's typically a 1 week turn around. Better than a kick in the teeth.
