applescript: curl / do shell script <--- getting progress

Since panther has now killed ftp upload, and I’m forced to use curl, is there a way I can show the progress bar of an upload?

Huh?

tell application "URL Access Scripting"
	download "ftp://ftp.server.net/dir/path.txt" to "Macintosh HD:path.txt"
end tell

Works for me (given a valid URL, of course)

“Huh,” indeed. What does this download script have to do with uploading?
