Can you comment on the problems you ran into with LFS?
Also it's very slow for small files, and the filtering is according to file extension.
So e.g. if I have some massive mp3s for (sometimes many minutes of) music but also many (100s-1000s) small ones for sound effects downloading 1000 small mp3s take a couple seconds per file even if each is only ~40kb big (normally download rate is a couple MB/sec).
