They are at least offering an escrow and promising the specs within reason or they will refund. As soon as I get the escrow agreement I'll post it here. I do wonder about the hosting requirement. I would much rather run the unit interdependently.
This is great feedback. By "hosting" we're not meaning that the devices need to be plugged in or online 24x7 to access a site hosted by LargeCoin. We issue you a token, and the token permits a certain number of blocks to be mined. For out-right purchases, the token will permit unlimited mining, whether the device is plugged in or not. And yes, the token is tied to crypto on the processor. As I mentioned earlier, the purpose of this mechanism is to support a leasing model.
