Co-ownership of domain and other intellectual property

I read somewhere that the development of society depends on the degree of trust of its participants. That is, distrust is a deterrent, and on the Internet, especially. Many would start working on partnership conditions, but this is possible if you have known your partner well for a long time. Although we all know a lot of stories when even old friends-partners diverge. And how much their project suffers from it. Most often, the domain owner has a significant advantage.

This suggests a service in which the domain is controlled by a third party - as an independent arbiter, and in the event of a conflict can judge the participants. At the same time, the project creators can at any time gain control of the domain from the service.

I think a similar situation with the management of other intellectual property: copyright, patents, software code, scientific developments ..., i.e. this service is also for them

There are several options for how this service should work, how it can be developed and several legal procedures that will underlie it.

The service may be non-commercial (possibly with paid additional services) and commercial. Maybe these services already have? How relevant is this service for you?
