I've become convinced that the nifty progress info doesn't get created when I invoke scp from a script, probably because scp has a call to isatty. Any quick and dirty way to tap into the progress info?

I've seen those types of programs when trying to make progressbars for various apps run from Tk. One of the things I've had success with, is running the program thru IPC::Open3, and watching the output on the filehandles. A sneaky trick is NOT to open the program itself with IPC::Open3, but open a "/bin/bash". Then print to the STDIN FH , your scp command (don't forget a newline :-) ). Then you should be able to read the STDOUT and STDERR that would be appearing in the bash shell. Regex that output for your progress data.

There are a few variations on this trick, like try a piped-open instead of IPC::Open3. Maybe 

open(FH, "/bin/bash -c $scp_string 2>&1 |");
