After a lot of work, I got it working with the latest version and have put my binary here. It now does uploading via SFTP. I haven't put all the libraries that ship with the source, but this is the minimum that seemed to work for me.

If you were looking for sourceforge utils at limegreen you'll have to download the whole ant template and extract the sfutils files from within the tools directory.
I've now put the files here, because there were a lot of library files I hadn't included within it.

Library files can be found here (you don't need the ant prefixed ones)
