+### Virtual Relays
+
+Some relays want to expose "virtual" addresses to the same underlying dataset or other types of weird functionality. A basic example is a relay that may serve all notes under its `/` path, but only Italian notes under its `/it` path and only Japanese notes under its `/jp` path. In this case clients may use the virtual (`/jp` etc) paths when browsing the relay, for example; but in other situations, like when selecting relays for building a feed for some specific profile, clients should just want to connect to `/`.
+
+```json
+{
+  "virtual_path": {
+    "is": true,
+    "canonical": "/",
+    "alternatives": [
+      {"path": "/jp", "description": "only stuff in Japanese"},
+      {"path": "/it", "description": "only stuff in Italian"},
+      {"path": "/fr", "description": "whatever"},
+      {"path": "/pt", "description": "blergh"}
+    ]
+  },
+  ...
+}
+```
+
+- `is`: this is `true` when the current path queried is a virtual path.
+- `canonical`: this is the path that should be used when the client doesn't care about the virtual.
+- `alternatives`: optionally, if a relay wants to announce its virtual paths, this may be useful sometimes.
