Say they do have to be in proximity, they don't have to do the delta at that exact moment, they can say "do it at this time". They don't need to be in a large crowd.
Correct. Phone call and texting via non secure methods would definitely be stupid.
Assuming what Q said was correct about Q being a group of people. Do you think they are always together? I imagine military intelligence has very secure ways to communicate that we are not privy to. Hell, even just using public encryption allows people to securely communicate. Unless there's a quantum computer that can hack encryption. Otherwise it is very difficult and would take decades to hack using the best super computers we know of.

They still have to be able to communicate that time to each other, which they can't simply do over the phone or through texts.
