Use Croc in lieu of Wormhole?

### Is your feature request related to a problem? Please describe.
It's immaterial really, but, I usually prefer croc to magic-wormhole. It's been faster and easier to install for me. It's also written in go, so IDK if it's easier to integrate than wormhole is and thought I would suggest:

Either way is a really nice feature!
