Indeed, I'm wondering about that too :) I found this: https://github.com/smallfish/ftp.go
At a first glance, I don't like its API very much. Alternatively, we can use wget but it will work on unix-flavored system only. Or we can write a better ftp client. What do you think?

ftp.go seems quite useless
