Robin Good's insight:
Gruveo is a secure and free web app which allows you to easily start a video-conference session with anyone without needing to register, download, install or login anything.
To start a video session you simply input a numeric code (of three or more digits) of your choice on the Gruveo home page and then communicate that code to anyone you want to video call. That's it. Your computer and the other device will automatically create a direct connection allowing your video conversation to start instantly.
An excellent solution for instant video calls that require zero set-up time and which may benefit from secure encrypted communication and anonymity.
Free to use.
