Peeriod is an open source project which strives for making privacy protected peer-to-peer file sharing available to the masses. Peeriod’s aim is to construct Onion Routing on top of a DHT, while at the same time avoiding certificate authorities. Each node is equally (un)trustworthy and can act as a relay node for encrypted traffic. A flooding-based search takes advantage of the DHT’s structure and provides full-text search capabilities.

Very basic PHP implementation for a HTTP node discovery server which is currently used to find an initial entry node.
If you want to provide a node discovery server yourself, adjust the credentials in db.inc and put it somewhere outside your webroot. Then specify the relative path stored in the variable $pathToDbInc in both index.php and build.php.
Run build.php once to construct the table structure. Delete the file afterwards and tell us about your node discovery server.
