i use teleport pipes on my server. All user have access to them. And seems to work.( need a world anchor at each end ).They are visually bugged, you don't see items coming in,but they do just fine.another problem i got is client side. sometimes when you click a pipe you get an error and disconnect from server. A client re install fix the error and all is good. It happen to me once. and 2 times to other users. Running the server for 7 weeks now. so is not a commune problem
