Welcome back @bkbonner!
I definitely like this idea.
There’s a Wishlist item for computer viewing here:
You might want to add you idea there. You may be able to do this using APK Mirror, but I don’t have any experience with it and I’m unsure how stable it is.
If you only need to view the cameras, you should try TinyCam. It can be unstable at times , but works well for watching the cameras. You can purchase cloud recording services from TinyCam, but it’s not worth it if you already use Cam Plus on the SD card.
