Even better, why not use OpenBubbles?[0] It's even better as it does not require the Mac to act like a server. You just need to collect its hardware identifiers once and you should be ready to go.

From skimming their website, that seems to be an Android app.
Edit: digging more on their website, there seems to be a way to host it on desktop Linux. The main page makes no mention of that.
