Is it the same animated-QR-code communication as used in Ywallet? In other words, if it is not one already, would it be possible to make it a standard so we can use older Android devices as budget offline wallets?

It is the BC-UR standard, which is widely adopted for use with Bitcoin. See here for some sample code I used to test QR sizes and number of frames for various file sizes (this is not tested for interoperability).
