Is there a Ruby on Rails based torrent tracker?

I'm looking for a torrent tracker written in Ruby on Rails (TBDev.net style or so). Is there a ready made package?

Another option: Is there a robust torrent tracker software tha开发者_如何学Got can act as a backend for which I can write a RoR front end?

BitTorrent tracker backend is a relatively compact piece, take a look at https://github.com/shurikk/bttrack that is just an example

Something like the Hydra Project? It seems to be abandoned though.
