Earn money for SW is very good idea, but on the issue here really is, for example I bought 8GB flash drive that I install emteria, and if I decide to bring the licences to a new one because lack of space on this tiny hard drive to a bigger one like 64GB or because it deteriorates then it is not very fair to buy new license for that issue, isn't it?
By the way I think emteria is very good platform. Best regards to the creators!
