how did a specific operating system get its own nip number??
Discussion
Because the signer communicates via Android inter-app APIs that don't exist anywhere else.
so it's an android specific form of a pipe file as per posix
i don't see why this can't be applied to all operating systems, that would be nice isolation... really would just be a matter of having a client specific key to auth with to sign requests and authorise getting responses, android does that part for you but it's the same same really
Yep. I think someone tried to replicate on a desktop signer with socket files in the home dir. It's all about specifying a good standard for the communication.
