Unfortunately, like I say, I've tried that (using Thunar - the otherwise fantastic file manager in XFCE). I'm not sure if it's Thunar's fault, or it's the FUSE layer beneath it, but I've always found it to be a little unreliable. Plus I like to be able to see connection logs and manage the activity queue in the same way I do with FileZilla.
