As long as the relationship between the teams is and stays a true collaboration, I see no problem. If the relationship ever devolves to one where one team has any sort of control over the other (e.g. the first team designs the robot for the second team), basically any situation where "collaboration" does not describe the relationship of the teams, then some students are missing out on important aspects of the FIRST experience and I have a problem with the situation. I think this is a very slippery slope, especially when teams are sharing workspaces and/or one is not yet fully developed, but if proper precautions are taken, this relationship can certainly be beneficial.
