There's something similar-ish... if you have an Apple TV and install VLC, there's a feature that allows you to upload whole video files across your local network, and then play them directly from the Apple TV. It's a bit less conveient than Beamer used to be, but still good enough.
Another past paying Beamer user here. I used it until it stopped working, didn’t update, then was bought by another company for redevelopment and incorporated into a horrendous subscription scheme, compete with hard sell sales.
