iPhone + Controller + Reef. What Works?

[PoonTang]

I may be looking for a controller in the future but dont know which one to get. I want something for lights, temp, pH, dosing, alarms etc. I would also like the ability to check on all of the parameters with an iPhone. Email alarms would be nice too. I will also be setting up a webcam on the tank at some point. Is anyone currently doing this on their tank? What would you suggest?
