So you need nips that implement those features, not nips that integrate PGP. Some of them are already actively being discussed. They can be turned into nips as soon as some major client implements them. You could help both by participating in the discussions or implementing some of the proposals.
Discussion
Well, if reinventing the wheel is the way, ok. I don't really mind about the method used.
I don't have the knowledge to implement them otherwise I would be doing it instead of asking for it, but I'll try to participate on the discussions.
Thanks.
It's not reinventing the wheel if it doesn't already exists. If it already existed you wouldn't be asking for it.. So...
