Diet Coda lets Web developers leave their notebooks at home. The $19.99 code editor for the iPad from Panic, Inc., is portable friendly, including an adaptive keyboard that tunes itself to programming languages for making it fast and easy to work with remote files.
Remote code editing using FTP or SFTP is configured separately from SSH terminal access to the same server. You can see the FTP/SFTP configuration screen for remote file editing here. An arbitrary file name can be assigned to identify each server. The usual information required for remote FTP access is provided in the rest of the configuration screen. Ports other than the standard TCP port 21 are supported.
