Another FTP program
Jomosoft has a new Macintosh FTP client, osXigen. It's MacOS X only, but seems to have a nice way of mirroring Web sites cleanly while letting you specify exactly which files you want to share and which (templates, design notes, etc) you don't need on your server.
At the moment, I'm quite happy with the new Fetch. It was written at Dartmouth but its author, having won a lot of money from Regis, bought his work from the university and now supports it professionally.
