[Feature] Support i2p

[ghbjklhv]

Objective: Implement and Support i2p in Matrix
Description: Explore the possibility of using Matrix over i2p.
Would non-i2p users be able to still communicate? Would you need to craft a bridge?
Why?: Many reasons, mainly for privacy and security but also to support decentralized communications.

I know that tor can provide fake 'ip' that are mapped to hidden services internally and act as a dns server to serve those ips to non-tor aware application, does i2p have something similar?

since I had to google for it, I'll save someone else the bother: I2P appears to refer to https://geti2p.net/. Some comparison to Tor at https://geti2p.net/en/comparison/tor.

Would be good to see this and Tor/Onion sites and IPFS/Unstoppable Domains support without the clients like element needing to work with I2P, Tor or IPFS. If the synapse can support I2P, Tor and IPFS then matrix can be really decentralised and unstoppable.

I2P support would be awesome

Why does I2P have to be part of the homeserver? Just run i2pd & use a supporting client (which seems only to be quaternion as far as my searches have led)
