I'm streaming from my phone with my WiFi disabled... anyone else manage to do this?

This is perfectly normal and how it's supposed work. You are not streaming from your device but rather your device is the remote. Once the link or signal has been sent to the cc you can go as far as pulling the battery on your device and the video will still play.

Exactly this. It's also in the FAQ Part 1, 1.d

In the Plex thread we also tested and verified that the Chromecast does not need an internet connection during local streaming from Plex media server on your PC.

It does need an internet connection to phone home to Google when you first connect to the Plex media server on your local network. But after that it will keep on interacting with the controller and playing new selections from the server over the local wifi network even with the internet disconnected. It only needs to connect to the internet again if you disconnect the controller from the Chromecast and then try to reconnect it. At that point the Chromecast goes to black screen and freezes in a wait state if there is no internet connection. But it resumes the local connection seamlessly if you restore the internet connection.

I knew CC doesn't "stream" in the traditional sense but for some reason I thought it required the device of origin to always be connected to the same WiFi network as the CC.

It's only the case (that the device of origin needs to stay connected) when "forwarding" video from another source and when the source data exists on the origin device. For example, Avia can pull from a DLNA source and push that to Chromecast, and both Avia and RealPlayer Cloud can cast local files to Chromecast.

If Chromecast is using its regular "optimized" playback from a streaming provider (HBO GO, Hulu Plus, YouTube, Viki, Pandora, etc) then the origin device is not needed after the cast starts. That's one of the things I like about Chromecast - you can start playback on one device then move to another device to control playback if you want or need to (for example, your kid decides they really want to play Angry Birds on your phone).
