AnySay

AnySay extends your neighbourhood and allows for public offline communication with people nearby.

It's offline:

AnySay uses wireless LAN to connect to neighbouring peers. No mobile network or Internet connection is needed.

It's peer-to-peer:

AnySay peers within reach form an ad-hoc network. Inside this network most recent messages are stored and redistributed. The number of messages stored in the network grows with the number of participating peers.

It's anonymous broadcast messaging:

AnySay is an anonymous broadcast messaging service. Messages have no single recipient but are distributed among all participants. In addition to broadcasting its own messages, each peer acts as a relay, forwarding messages from other peers. This forwarding mechanism provides anonymity, since with an increasing number of peers it becomes harder to find the original sender of a message.
