Yep :) And I know Bernhard was hoping to get in touch with Roger
on this before long.

Basically, prop224 HS being wider than 80 bits will break onioncat's
current HS onion <---> IPv6 addressing mechanism.

They're looking at various backward compatibility options, as well
as possibly making side use of the HSDir DHT, or even integrating
more directly with the tor client.


Onioncat v1 is here:

I wanted to link you out to the recent onioncat list threads on v2,
but that list and its archive is down right now pending them getting
it back online. I could forward the posts.

Readers of tor-onions / newbies may have been unfamiliar with
onioncat. It's a way to get non-TCP between TorHS onions, thus in
the thread "Hidden datagram service".

I think there are a nontrivial number of users interested in, and
using, non-strictly-TCP transport over an IPv6 tunnel interface.
For example, look at users of CJDNS...

For which we should try to continue a way, in v2, to do that over
anonymous overlay network Tor / I2P.

Sounds good, especially with the onioncat list being down right now.

Onioncat list had reliability issues in the past, maybe torproject
would like to host it and import its ezmlm and mailman archives?
