Overview
Perfect Dark is still being actively developed. The author does not ask that the program's users at this point become dedicated "users" of the software. Instead, the author asks them to participate in the test phase. Through this test phase, the author hopes for bug reports and discussion that will help shape Perfect Dark into a better program.
Perfect Dark has higher bandwidth and hard drive space requirements than its predecessors Winny and Share. The minimum upload speed is 100 KB/sec, and it requires at least 40 GB of hard drive space for its "unity" (cache) folder.
