A good lesson that though someone could build it, most can't and if they could they'd rather not.

There's a really easy mental shortcut engineers or engineers who are aspiring entrepreneurs can make.

It starts with a thought like: "Oh, I can do that by gluing together X, Y, and Z and configuring the foobaz widget to sync via the 802.11q network."

Your second thought should be: "No normal person could do that, and even those who could probably wouldn't want to."

I remember that after "Find His Porn" website was featured on HN (https://news.ycombinator.com/item?id=3301137) someone here presented an application that does the opposite - provides hidden, secure, encrypted drive - and that basically is TrueCrypt + some magic scripts that make it normal-user-friendly. Can't Google the link though.
