Federated is nice, but with Radicle you don't need a server with publically accessible IP, so you can pull and push with just a node running on your laptop—though I understand there still need to be some nodes with publically accessible IP due to NAT and it doesn't seem Radicle is (yet?) doing NAT punching/STUN/TURN.

Well, at least you don't need a name or a certificate for the server, I assume its id works as its cryptographic identity.
