Portable Feeds Idea for Gemini

I've been pondering this as a way to have portable feeds for gemini. At the moment, the links that I have subscribed to are local to my gemini client (Lagrange most of the time).

One way to make them transferrable across clients would be to just share a gemini page linking to each of the subscribed pages. I could put it on this web page. Alternatively, it could be behind a password or client certificate authentication to not share the pages publicly.

Gemini clients could be enhanced to better support use of a local gemtext file as a source of feed subscriptions...

I gotta play with this idea a little.
