[PD] Can you close source of Pd patches (for commercial development)?

[Matti Viljamaa]

I’ve been thinking about the feasibility of leveraging Pd as a development platform for commercial patches. Sort of like some (e.g. Twisted Tools) are using Reaktor for developing commercial-grade plug-ins.
But instead of Reaktor I could rather use Pd, because it’s a more open platform.

But if the development is for commercial purposes, there would need to be some sort of mechanism for closing the source. Is this possible or something worth looking at?
