You could make a lot of money by keeping the ASICs for a couple of months before releasing them... 
Worked well for BFL /s
Not the best business model.
and where bfl now? sinking in taxes..
Too true, and the "keeping the ASICs for a couple months before release" is not what we will be doing. We will test each one yes, but then immediately put it onto the host and enable the users pool proxy for each unit based on order in which it was ordered. (This is why we are not taking orders until everything is ready, to avoid confusion on our parts later.)
We plan to ship the secondary hosts the units they will retain once the units are paid for and as a lump shipment. We wont be doing 50 shipments to a single secondary host. So that will likely be the only delay, shipping to the secondary hosts.
Ye there should be some limits by the first batch like 5 units for the single host or maybe max khps pro person or address.
