Mike: so sorry, I didn't bring a camera. I couldn't find my SD card on the way out the door, so I left it behind.
Rupp: I'm not aware of any patent that prohibits Sirius from making a 2-way remote. But then again, I'm not a lawyer

As far as prices go, I see manufacturers coming out with smart switches and smart devices at a range of price points, based on the "fit and finish" and feature set of their devices, just like it's done with non-smart-switches. For instance, the Leviton Acenti line demands a higher value than standard Decora switches; the same will likely happen with smart switches.
The Sirius 2-way remote is, I'm sure, interoperable with all other Z-Wave devices. I haven't seen any issues where any Z-Wave device is not interoperable with 1st-, 2nd, and now the 3rd-gen devices. Are you asking if it will automatically turn "pollable" devices into "live status" devices, though? If so, no--that's a feature choice of the devices themselves, and not a Z-Wave thing. That's another one of the marketing differentiation points I see in products.
BTW, Linksys is here at the Z-Wave booth as well, indicative of things to come (likely related to the Cisco Zensys investment). Every time we visit a smarthome-related show, it seems like yet another one of the industry giants has started producing Z-Wave devices. And many, many more are working on things.
If any of you get out to the show, you need to go check out the Z-Wave pavilion (and Monster in the next booth) and see all the cool devices working, from the various manufacturers. BTW, I noticed that some of the product lines were not even represented at the show--those will be on display at IBS next week instead. That will be a show not to miss too.
