In the Gemini tradition of multi-schema URI support you could even use
a Bittorrent magnet: URI.  As long as you the capsule owner are seeding
the torrent, it's just as good, and doesn't require a third party
hosting service even if your capsule is on restricted shared hosting.

For simple files like images, PDFs, or EPUBs, Gemini itself will be
fine.
