1) I see what you mean. I need to make more use out of that area.
2) I agree. Twilio is pretty inexpensive, so I may go ahead and integrate with them. At first, I was seeing this as less of a near-real-time service and more of a, "hey, heads up" service, but I can see real value in providing more immediate monitoring and notifying.
3) Great point. I'll definitely add this to the FAQ, and FYI, it's polling every hour right now. As I mentioned above, I'm rethinking this, so I'll probably decrease the polling wait period significantly and I might make it user configurable. The connection is very light weight, so it's easy on my server and the clients'.
I'm glad you think it's a good idea. There doesn't seem to be much interest yet, but I'm still optimistic!
