Plugin for connecting an IPFS swarm over i2p
WARNING: This is only for forwarding the local swarm port over i2p, not for connecting to i2p-hosted IPFS instances. It will not route communication between IPFS nodes over i2p(1). This means that it doesn't make your IPFS instance anonymous, it just makes it accessible to clients anonymously(2). As such, it's probably not that useful to people in general yet. It's also emphatically not a product of the i2p Project and doesn't carry a guarantee from them. File an issue here, I'm happy to help.

(1) I'm going to do that too, but that's the hard part(the plan is to adapt BiglyBT-style bridging, with a pure-clearnet peers, clearnet-to-i2p peers, and pure-i2p peers. That may be less straightforward than the simple description made it sound).
(2) Of course, that leaves the matter of i2p-compatible IPFS applications but those are almost as simple as the gateway.
