I'm looking for an FTP client that can connect to two different FTP servers at the same time and allow file transfer or synchronization between those two servers. Basically what I want to achieve is to transfer/synchronize files between 2 different sites from my local machine. Are there any clients around that support this functionality? If there are none, is there an alternative to achieve this?
I've taken a look at net2ftp, a web based FTP client, which provides almost the same functionality that I need. What I'm looking for though is a desktop app. Any ideas?
