Fontstand is a really interesting new app for Mac OSX that allows you to licence desktop fonts via a rental pricing model. You can try fonts for free to see if you like them, and active them via one-click in your favourite design applications.
High-end fonts can be very expensive to purchase, so a rental model will make sense for some designers. It’s also worth pointing out that if you rent a particular font for 12 months then it becomes yours to keep on a permanent basis.
