Good to see I2P get some attention here.
For those who don't know about I2P:
* Anonymity network similar to TOR in some ways, but rather than focusing on getting someone out to the internet anonymously, I2P is a low-latency mix network with no out proxies. See: https://ritter.vg/blog-mix_and_onion_networks.html
* Virtually every I2P router relays traffic, unlike TOR the network is very "flat". Directory servers are replaced with a DHT called the netDB.
Recently I've been working on a Go implementation of the I2P router: https://github.com/hkparker/go-i2p. It isn't on the network yet, would be really interested in working with anyone who wants to contribute.
