progress bars

I have read some former posts about Grip progress bars only being a guess.

there has been some work on pipe programs that given some parameters 
(e.g. input file size) transparently pass standard input to standard 
output and give progress indication on standard error. One such package 
is cpipe (http://cpipe.berlios.de), although the functionality is 
similar to the program movie-progress in the videotrans package 
(http://sourceforge.net/projects/videotrans).

This could at least show how much of a .wav file has been passed to an 
encoder, provided that Grip can read and correctly interprest data on 
standard error.
