put.io also supports "ftp’s, direct download links, many paysite links, basic http authenticated links" (http://put.io/features). So I guess fetch.io has less features :)
the free part will be totally useless. we've seen so many sites trying to do this for free. none of them work. imageshack closed it down, put.io didn't even try, torrific is so slow, you can write data faster by hand
