From what I understand, using another layer of encryption (ssh) over the tor network is redundant since it is already secure.
I2P's encryption is probably much better.
no they are about the same.
only that i2p's encryption is more obscure. and obscureiry only leads to holes and flaws.
http://en.wikipedia.org/wiki/Security_through_obscuritytor's code is clean and simple. i2p is obscure and diffecult to understand.
