We have a handful of FTP and SFTP plugins. I'm not sure if they're advertised or used much by Titanium Studio users. We may want to break out an S/FTP feature (and repo?) to move them to, build them separately and then include them under the Aptana Studio umbrella so they don't get installed in Titanium Studio by default, but only in Aptana Studio (like we did with Ruby/PHP/PyDev).
We already have the S/FTP library in it's own feature and build. It would likely be combined with the following:
deploy.ftp, filesystem.ftp, filesystem.secureftp, syncing.core, syncing.ui, ui.ftp, ui.secureftp
