I like the idea, but I think it would be kinda hard making it work. Then there is also the problem that you would try manipulating the same polygon/scenery/whatever at the same time someone else is doing something with it.
Also the todo list on PW right now is kinda packed with things and I dunno how many ppl would actually use this, but if it gets enough support I might think about it.
Btw, these type of requests should probably go in the Soldat PolyWorks topic, not as a new topic in the
fan apps section.
