[TriEmbed] OTA updates on ESP8266

[Mike Lisanke]

This guy's videos are great And he's developed a system+library for OTA
ESP8266.

Using Anybody else's system for OTA programming has an inherent security
concern
and even leaving the ability for OTA without end-user interaction leaves
you open to concerns...
so, think carefully about what you choose to do... if you're concerned.

A large number of hacks have been accomplished with bot'ed IOT devices. And
engineering
security into systems is inherently difficult.

If it's just for you, and it's an Internet aware device, then it'd be easy
to create a custom
p2p solution Only you could program... for a device manufacture, that's not
so easy.
