Forget about cyberduck, the real thing is made possible by Amit Singh!! Two visitors dropped comments about about the release of this project. I’ve updated the post that I made back in September.
Until then… I will use cyberduck!!!
Cyberduck is an FTP / SFTP client that let’s you browse filesystems on systems you have ssh access to. It not only lets you upload and download files, it also file edit support. After connecting to a server, select a file and right click it. Select ‘Edit with > Smultron’.
Cyberduck monitors the file that you just opened in Smultron. If you save it, it will be automatically uploaded to the server, just like you where editing a local file.
And, of course, both Cyberduck and Smultron are Free and Open Souce 
Neat!!
