Looking for something I can setup to transfer files from my home iMac to my folks' MBP over the internet. We use iChat (via Google mail) often, and I "take over" their MBP to perform maintenance and just generally help them when they get stuck (they're not very computer literate) however, I would like to have a way to transfer files that are too big to email to their machine i.e. video clips etc. Any recommendation for some sort of FTP application would be much appreciated. I've used FTP software on Windows machines before, just haven't used anything on macs yet. Thanks!
