on CPAN and it looks to be pretty well stale. I was thinking of starting work on something similar to bring it up to the current level of clients out there (ultra peers, swarm downloads, checksum passing etc). Before I go charging into this, I was wondering if anyone knows of any other modules that are more up to date with the current protocol (and advanced features). I have done quite a few googles on this but have not been able to find anything. Any info you know of would be great -- I don’t want to reinvent the wheel if I don’t need to.
