Room Size
Currently the room size limit is 20. This will probably be exposed later in an option, since a free-for-all chat can be pretty noisy if people don't apply restraint. If you come in and the room size is over the limit, the application will log you out and display a "room full" message, with a counter showing the time in seconds before it attempts to reconnect (currently 30 seconds).

Usage Limits
During the Walkie-Talkie Widget beta, there is no time limit for live chatting. This may eventually change depending on bandwidth usage, etc.

Idle Timeouts
If you load the page and don't do anything for five minutes, the Walkie-Talkie Widget will turn itself off. Clicking on the talk button even once will disable this. This idle timeout might be exposed as well, depending on feedback.

Abusive Use
If you hold down the talk button and max out the input volume for 5+ seconds, it will un-click the button for the user. It won't ban the user for repeatedly doing this, but that's a possible feature addition... other limits may be considered as requested. Let us know – support@yackpack.com
