Guys, Thanks for drawing my attention to WinSCP. I never knew it existed. I've been struggling with FTP'ing into an ibay, then using PUTTY to move the file elsewhere on the SME box.
This will make life lots easier (for web admin especially) as I deny FTP from outside the local network. I've just got SSH shared keys working from the entire internet, and have turned off password logins. Just tried WinSCP with my private key and it works a treat.
