This is just sort of a brain-dump post :).
As I see it, there are several ways I’ll be able to open my garage with my SmartThings:
Use a Evolve LFM20 or other similar big honkin Z-Wave relay. These are designed to switch full 120vac but should work fine to close the circuit to the garage door opening button.
Use a big ZWave outdoor module: http://www.amazon.com/GE-45604-Technology-Outdoor-Lighting/dp/B0013V8K3O to power a relay. I’d have to tell my SmartApp to turn it on then immediately turn it off.
Use this ZWave MIMO device made to control garage doors and other small devices:

- Use a Zigbee device made to control garage doors and such:

Use an Arduino and the SmartShield (wish I would have picked one of these to get with my kit, kicking myself now) and a little relay.
Use an Arduino with the Ethernet shield. SmartApps can interact with services over HTTP (using HTTPGET) so I could easily have it send a command to the arduino to toggle the relay for a second. Since the SmartApps run in the cloud, I’d have to poke a hole in my firewall (I’ve got static IPs and all that)… I could probably restrict the incoming connections to SmartThings’ cloud.
I’ll probably do #6 until I can get my hands on a SmartShield or a MIMOlite.
