It's fine, it was mostly just a curiosity question. I spammed a bunch of packets at the server and it seemed to crunch through them without dropping any and works great for this use case. I might take a crack at a queue system at a later time.
I found that I have a 9 tick delay to send and get a response back and it takes 1 tick to send a modem message, so I'm guessing that as long as I don't send much more than 9 client messages at once without switching to an event pull then it should be fine.
