Bootstrap via Cjdns

I noticed that all of the IPFS infrastructure (bootstrap) nodes are reachable via Cjdns.

However, only a few Hyberboria peers (transitiontech.ca, h.amadeu.berlinmesh.net, …) have a direct Cjdns connection to these nodes. Would it be possible for others to peer with these nodes via Cjdns directly as well? This way one could bootstrap IPFS via Cjdns only?
Or is there a special “application process” to get a peering credential?
