It would be very great if 2 test engineers would be able to work on same project in same time in SoapUI.
Or at least there should exist some kind of "merge tools" that takes changes from project1, project2, ... projectN, and merges those changes to one "master project". This functionality is very needed when services are already defined in SoapUI and you want to make test-cases corresponding to each service and you want to derivate this kind of work on more than 1 people.
This is not posible right now and you have to merge changes manualy (via total commander for example).
