"Send to" for Open Brush and other apps

[andybak]

Open Brush listens on port 40074 and you can do the following:

http://localhost:40074/api/v1?model.webimport=https://s3.us-east-005.backblazeb2.com/icosa-gallery/poly/dLHpzNdygsg/Astronaut.glb

Poly.pizza uses this for it's "send to" feature:

We have a server listener plugin for Blender as well that works in a similar way.

That also has a "ping" endpoint so a further refinement could be to disable the button (or link to instructions) if Open Brush / Blender etc is not detected.

We need to consider security here as any link on any website can send messages to a running app. Open Blocks has a few restrictions to mitigate this but we should have a hard think about realistic attack vectors.
