I think GNUNet GNS system is really nice. I wish they would find an application that actually uses it.

The problem with all that GNUNet stuff its that its almost all research, no real active open source project built around them.

I really like re:claimID, basically OpenID Connect auth against your local device. But it would of course need much more work to be practical.

Overall its all very cool and this is in no way criticism on anybody that works on it. I am just point out to people that if you want to get involved or build on top of it what it is.

I would them to work together with some of those Peer-to-peer chat systems or something like that.
