I hope not — there is no reason to replicate the misguided packaging
design of Tor project's various “bundles” elsewhere.

Unfortunately, this addressing scheme apparently cannot accommodate
other anonymous networks, such as I2P, that uses 256 bits for its
Base-32 addresses.

The .onion – IPv6 mapping is a bijection, the unique local IPv6
address represents the same information. It apparently even complies
with the RFC, as .onion addresses satisfy the randomness requirement.
