Over time, quite a number of people have responded by building nodes and libraries. Check out Libraries — XOD . Of course, that depends on the generosity of the developers. Also, for hardware, it is difficult to develop nodes/libraries without having the hardware.
Do you (or anyone reading) have any experience with commissioning paid development in this sort of context? I’m thinking of “bounty” sites, project grants (cf. Perl Foundation), or something more like contract work. Some mechanism that is fair and trustworthy for both/all parties. Perhaps a mix of paid work and free contributed-work (“buy 4, get one free!”), if it makes economic sense.
