Love it!! I own the domain internet.inc that would be perfect for this - want to use it??

They have a GitHub and you can self deploy it on your own domain... use their infra, pay their fees.

> The problem is that it requires shared mutable access to that state, which is clunky at best in Rust (it requires interior mutability).

I don't see the problem with using interior mutability (Rc<RefCell<T>> or Arc<Mutex<T>>)

With Slint [1], we just embrace it, and rely on interior mutability for the shared state, and that works well.
