My mom gets tired of computer stuff, but she's still set up a router with port forwarding and installed parts in a computer before. Last week she was trying to get her cloud dvr working so she could leave her house while her mare is in foal.

I think if you build something that's internet-connected you could probably stand to ask yourself whether someone like her can use it. She may try, after all, and she's definitely the kind of person to leave frustrated reviews of your product on Amazon.
