Honest discourse for the purpose of highlighting any possible issues and fortifying against the EEE process. (Prepare for war; hope for peace):
Let's say they were able to join... (We should at the very least go over this possibility, as it can also help our admins decide.) How would we be able to protect our network?
Would making sure any features of one instance/app be open and able to be modified and/or gracefully integrated into another be an option? (similar to the GPL license) An example would be keeping a party from restricting access to a private network only through their app. (looking at you, gTalk and iMessage)
Any other suggestions?
