Wow, really great idea and looks so simple to use.

The more important question is, are they running mainline Linux, close to mainline Linux (like Raspberry Pi, or outdated much modified unmaintainable vendor and device specific fork (like Android phones do).

Because borning a child yourself is the purpose of life and without it there is no sense in living.

There is compatible C++ version named i2pd.

Even less content. But I2P is cool.

If have open port than I2P is faster (still not fast, but much better) because you actively contribute to the network.
