From the developer:
Hedera is a peer-to-peer (P2P) file-sharing program for Mac OS X, built atop the giFT daemon, and based on the excellent-but-now-outdated program Poisoned. It supports five networks and uses the giFT daemon. The search filter now properly disables itself when nothing is selected in the search list.
You may want to check out more Mac applications, such as Unofficial RapidShare Tool, nicovidedownloader or kFTP, which might be related to Hedera.
