[lnsncsbf] Buy a cloud server

Instead of renting a computational cloud server, have a way of buying it (renting it permanently) for a single payment.  However, you can return it (at a depreciated value) or transfer it on the open market (forcing prices to remain sane) when you don't need it any more.

Probably won't work for businesses, but may for consumers, who don't like the idea of a constant drain on their finances.
