In case you don't know MuWire is a LimeWire offshoot for I2P. And if you don't know what LimeWire is, it's comparable to a torrent client with an embedded search. It doesn't use torrents, but another protocol.
/u/zlatinb (don't know if he's here) is the writer and afaik, it's directly included in the I2P router and also has a docker image so you can run it on a machine that's separate from your I2P router.

It's pretty cool, but just make sure you upload your files through the browser via the drag/drop function and not direct to your server via FTP (they won't show up as uploads in MuWire).
I have crappy net so I don't really download or share anything but I've poked around and uploaded some ebooks about ham radio and building log cabins or something as a test.
