you also have to setup eshop and accordingly shipping of stuff. i would suggest to keep POW period for a day or 3 and then go with full POS. but nice concept and watching this space to see further updates
good luck
Why would you think a 24-72hr pow would benefit this coin?
All that does is reward the first people in the door and doesn't really do anything beneficial for the coin itself.
Sounds to me like you only made that suggestion so you can make a quick buck.
