I’d say so. It’s way too easy to steal fonts as it stands. It makes me feel like it would be a really bad idea to attempt to create typefaces for anything other than a hobby. Why create a product that, as soon as it is released, loses it’s initial value because it is free in the eyes of so many?
It could work like the iTunes Music Store’s m4p format. If you buy a license for 5 CPUs, it would have to be authorized on all 5 computers. It would be a big harry deal to get implemented and for it to work across networks but it would be worth it.
