I had an interesting twist to this. I wrote Alarm Relay last evening after this discussion to ask if they sold them (figured they were nice, i would offer) and got a call back to warm me that the Uplink's do not provide any zone information, only alarm indication, that it could only be hooked up to the bell circuit (I think she said).
She also said my current setup was not sending zones (it is).
I guess just to make my certainty 100% not 99.9% I'm going to do a test run with the Uplink only no internet, but I found this kind of an inappropriate sales effort. And Alarm Relay has previously been very nice to deal with.
