Hmm, as far as I understand PayPal's classification, there is "crowdfunding" (money used to finance - more or less - every step of the project, and the outcome of it all not being guaranteed), "pre-selling" (company has other sources for conducting its business, and sells additional items, which it is certain to deliver, given that the underlying effort is already covered by those other sources), plus presumably a number of other categories not relevant in this case. According to this scheme, the Neo900 project would be very much "crowdfunding". As I understand it, it is PayPal considering us doing "pre-selling", which causes them to apply those restrictions. Again, to my understanding, the principal difference is that crowdfunding is a "best effort", where all parties involved accept the possibility of failure, while any form of regular sales, which would include "pre-selling", considers failure to deliver in itself as a breach of contract.
