I agree with others. There could be something like a 5-day grace period or a 3-day trial period. (Not sure the exact duration yet.) During this period, I should be able to setup a second NAS server on a new machine, and transfer everything from the old to the new one, and then disable the first one.
I'm asking this because I can foresee a future when I need to replace the whole machine for a hardware upgrade (new motherboard, new drives, etc.), and thus being able to temporarily run multiple machines under the same license would be a valid use-case with clear benefits to the end-user.
One could argue I could move my old drives to the new machine, but that's more dangerous. Doing so, there is a high risk of losing data, either by mistakes when installing/configuring the data, or by just hardware failures while handling the drives. Thus, even though it is technically possible to move the drives to another machine on certain cases, it's still safer to setup the new machine completely, validate it is working fine, and only then decommission the old machine. After all, reliability is important, right? That's why we are building NASes, right? Thus we need to have multiple machines under the same license during a short period of a few days (possibly up to a week).
Please consider this while planning for v1.0.
