I agree, but will I be generating too much traffic to be polling from a thousand computers every X number of seconds? Let's say X was 15. Every 15 seconds, a HTTPS web request and response (as small as I can make it) will be sent out.

Not sure how much traffic that would be, but seems like it is potentially quite a bit.

Wasn't sure if that was the best route or if I should somehow have "push" technology where my server would tell the computer they had something to do.
