Err, first of all it's name is i2p not ip2.

Anyways it isn't a unproven technology, it's a very actively developed project and has live working network which is very impressive.

Also the i2p-gnutella network has been growing nicely, so far at least 22 users have tried it, though the actual number of currently active peers is unknown (mostly due to some issues with the current version, which are going to be resolved in the next release).

Let me point out the i2p doesn't hide ip addresses at all, it doesn't try to do what is impossible. Instead it makes them no longer much of a issue, as all anyone can prove is that you are running a i2p node, not what any one specific node is transferring, nor which node belongs to any one specific member. Basically i2p has many perfectly legal uses (far more than any filesharing solution) and is more of a general networking privacy solution than a filesharing one.

So yeah the ip addresses are known, but so what in this case it just doesn't matter. Unless where you happen to live, they make it illegal to run i2p (only place in the world I can think of would be china).

Anyways the great thing about i2p is it'd be really hard to justify outlawing at least in countries like America.

The primary reason I struck back was because of the incorrect statements and assumptions that were being made. Nobody bothered to visit the project's website and read about what they were making judgements about.

Finally let me say I never claimed i2p hid ones ip address and I'm not sure why that was assumed.
