oh yeah, read about that one. If I'm right, it can even be constrolled by Skyrim's adult mods.

Hey, this forum seems pretty active on software development front, and i found an as of yet untapped resource of great potential.

The thing is called buttplug, and as far as i can tell, its an "online" interface that connects a bunch of wireless toys from fleshlights to xbox controllers, and allows all of them to be controlled through simple,unified commands.
https://buttplug.io/
https://github.com/buttplugio/buttplug-csharp/releases

Also, it already has a few applications: several versions of script players online, or downloadable that allows for your toys to play out the script files, to mimic the action to the corresponding video, be it VR, fap hero, or HMV, or just general porn. Its good stuff.
downloadable player:

online player:
https://syncydink.buttplug.world/
and the scripts to use them with:
https://github.com/FredTungsten/Scripts
https://github.com/funjack/funscripts
connect toys to buttplug, buttplug to player, load the script and the video and off you go!

Ofc, the real deal would be if you could connect the teasviewers to buttplug, then it would have real control over your toys.
Simple stuff like beat counter being periodic vibrations, with toggle switches for constant vibrations, on which toys, muting them, etc...
