Thanks for the reply.
So basically, if there was a way for some company to create a proprietary
software Myth module that is only distributed in signed, binary format, then
Myth could do DRM? Sounds like a business opportunity for someone! :) However,
I suspect the licensing costs to do something like this would probably far
exceed the Myth community's willingness to pay for such an add-on.
