Yeah well, unfortunately I think this must require a hosting provider. At best like if you push Nameservers to their extreme you can add a TXT record with Bio and a TXT record with a link to your photo, or use data URL to encode the entire image
.. and the Nameserver does the profile job. But if your Nameserver is so generous with storage, I suspect it can double as a Peergos server as well. The main difference is that if you put the profile in Nameservers, you can use it without having to use Peergos SDK.

I often tell myself the reason people tried WebFingers and Gravatar but never the same in DNS, is because no body has domains.
