Remember when Skype could call anywhere for free? Well here's a much easier solution (no software to install - it's an online, Flash-based caller). You can call anywhere using nothing but your internet connection and your mic.
Name an online room, then just tell people to meet you in that room. No software to install or complicated settings. MIght want to have a pair of headphones handy.

Control how and when switchAbit is activated by setting
