[freenet-dev] What we are really after was Re: Short refs was Re: alternative to #freenet-refs

[Matthew Toseland]

What exactly are we trying to make easier here?

1. Short refs:

We could make #freenet-refs no longer need a pastebin, which would get us a 
few more users in the short term, but given opennet is rather pointless.

We could make it slightly easier to IM your noderef, since it's a line to 
paste instead of a file to send ... but most IM clients (apart from IRC!) 
support sending files, and sending a file has the advantage that it can be 
automatically passed to the node if one is already installed.

We could make it possible to include your noderef as a line in your email sig. 
This would be useful in the medium term IMHO, although obviously not in the 
long term. If you're sending somebody a noderef intentionally, as opposed to 
just advertising, you'd actually include it. Also if they end up on mailing 
lists etc you end up with lots of ubernode connections...

2. One-time Invites

Invites are useful for offline connect, *provided* that the issuer is port 
forwarded and his IP doesn't change between issuing the invite and it being 
used. Could be bundled with a copy of the node on a USB key. Time limited, of 
course.

3. Really Easy Two Way Darknet Invites: SRP

:)

This would rock - you just exchange IP:port both ways, and a password. You 
only get one shot (or 3 shots, or whatever), so it's DoSable, but it would be 
*really* easy. You can e.g. write the IP:port and password (hopefully 
passphrase) on a piece of paper and give it to somebody.

If there is a DoS, you have to fall back to exchanging noderefs. However, you 
will know there is a DoS and therefore there is a Good Reason to go to the 
hassle.

SRP can either use a typed in password or we could have the node generate 
them. Again time-limited, and the password should not be reused.
