Immobile vore systems

I had a suggestion, which I also brought up to Ante in-world (the owner of SLVC). Although most people have their own vore systems and animations, it would be nice if the sim also had structures that pred and prey could sit on, which contain a hidden stomach and automatically position and animate both accordingly. This would make it easy for anyone without an own vore pose to eat others, as well as for predators to wait for their prey (which can sit on the proper poseball at any moment to get eaten by them).
This is the base idea: You have a chair or couch, which from outside looks perfectly normal. Inside or under it is a hidden stomach model. When no one is sitting, the chair only has one pose ball for the predator. Once the pred sits on it, a second pose ball for the prey becomes visible. If prey sits on that, they are positioned inside the hidden stomach. Optionally, the pred's animation can be changed, and a bulge added to them (perhaps by using llAttachToAvatarTemp). Prey can stand up at any time to get out, and if the predator gets off the chair first prey is automatically unsited too.
I already made a simple Vore Chair in the past, but the design wasn't too good and it's only for macro predators, so not much use here. I'm planning to make such a system myself at some point, but don't know when I'll get around to it. Has anyone else made one or plans to? The owner said that if a good chair of this sort is built, he's willing to add it to the sim... so it would be worth a try.
