Included with TRS22PE is access to a "Free tier of MPS". This implies that there will also be non-free tiers as well. Perhaps another subscription? I do recall that the concept of MPS being a subscription service was mentioned when it was first announced in December 2021. Further, it appears that the free tier will be limited to just the routes that N3V makes available to be edited much as it is now. I guess if you want to work with your friends to build a new route then you will have to wait for a future upgrade. Now you and your friends can go off to a corner and work together there but of course any other user could find your work and deface it. Also, to fulfill the need to balance the load on the servers, N3V has the right to shift users around between servers so meeting up with your friends might be pretty difficult in the first place.
