Monitor Shell Copy File Progress

I bet you could use cURL for this, using the FILE protocol. Build your 
curl command line with filenames formatted for curl; open it as a 
process for read; read that process's output every 500 msecs or so to 
get the progress info.

I'm on assignment in NZ right now so I don't have everything at my 
fingertips. Josh Mellicker made me aware of curl a few months ago, and 
Ken Ray may have made a rev library of it by now.  ;-)  Also Mark Smith 
created a rev curl lib some time ago.

Food for thought...
