Can I change the icon of a mounted disk in Transmit?
I did the following and it worked.


Open the .icns file by double-clicking it.
Press Cmd-C to copy the image.
Mount the FTP volume.
Click the mounted volume's icon on the desktop or in a window viewing the computer (Shift-Cmd-C in the Finder).
Click the icon in the top left.
Cmd-V to paste the icon in.


This creates an file at the root level of the volume called .VolumeIcon.icns, which when Mac OS X sees, uses it as the volume's icon. I successfully ejected the drive and remounted it and the icon was still there.
