Ventrilo Server Status
This tool helps to check if any known Ventrilo server is online or offline.
There is Channel Viewer Protocol used to return channel and users from API, so you can use any widgets that uses CVP (see example with Mumble-widget).
It works with Ventrilo server 2.x and 3.x versions, and correctly display cyrillic symbols.
It's definetely better and faster than official Ventrilo server status http://ventrilo.com/status.php.
