Conclusion
With so many ways of communicating into and out of a system, you must begin with a solid framework. My method
is to separate the input systems from the processing, allowing any input mechanism (mobile phone, e-mails, or web
interface) to generate a command in a known common format that can be processed by a single script. In a similar
way, all messages are sent to a single script that then formats the message in a particular format, suitable for the given
communication channel. You can also add an automatic process on receipt of any, or all, of these messages. So, once
you have code to control a video, light switch, or alarm clock, you can process them in any order to either e-mail your
video, SMS your light switch, speak to your alarm clock, or any combination of these.
