There's got to be a similar market for "push notification as a service". I wouldn't mind giving a company $20 for credits for 500 push notifications. I hit their API, they push to my phone with whatever text I give them.
What happens to all the old / retired scooters when something like this happens? I'd love to buy a "project" scooter and refurb it back to my satisfaction
Cowrie [0] provides an SFTP and Telnet honeypot and you can configure the filesystem to serve your desired files. Not quite a passthrough for legitimate use, unfortunately
An interesting alternative is Moonlight[0], an open source implementation of nVidia's GameStream protocol. While it does require an nVidia graphics card, it severely cuts down on latency as all the video encoding is done in hardware on the host PC. Essentially it gets you P2P low-latency video streaming with controller/keyboard+mouse input
